A {Review|Evaluation|Assessment|Examine}: The {Laws|Legal guidelines} Of {Series|Sequence} Circuits
In a {series|sequence} circuit {containing|that contains} two resistors and {powered|driven} by a battery, only {one|1|a single|one particular} electrical {path|route} exists from the plus terminal of the battery to the minus terminal of the battery and that {path|route} goes {through|via|by means of|by way of} {both|each|the two|equally} resistors. If you disconnect {one|1|a single|one particular} resistor, you will have an open circuit and no {current|present|existing|recent} will {flow|movement|circulation} {through|via|by means of|by way of} the other resistor.
{Here|Right here} are the {rules|guidelines} for {solving|fixing} {problems|issues|difficulties|troubles} in a {series|sequence} circuit:
{1|one}) The sum of the voltage drops across the resistors is equal to the voltage of the battery. If you have two resistors in {series|sequence}, then the battery voltage is the sum of the voltage across {each|every|every single|each and every} resistor.
{2|two}) The {total|complete} resistance is the sum of the resistances.
{3|three}) The {current|present|existing|recent} is the {same|exact same|identical|very same} in a {series|sequence} circuit. There is only {one|1|a single|one particular} electrical {path|route}. {Therefore|As a result|For that reason|Consequently} there is only {one|1|a single|one particular} {current|present|existing|recent} and that {current|present|existing|recent} flows {through|via|by means of|by way of} {both|each|the two|equally} resistors.
{4|four}) The {total|complete} {power|energy|electrical power} dissipated is the sum of the {power|energy|electrical power} dissipated in {each|every|every single|each and every} resistor.
{5|five}) The voltage across any resistor equals the {current|present|existing|recent} {through|via|by means of|by way of} that resistor multiplied by the resistance of that resistor. This is an {application|software} of ohms {law|legislation}.

A {Review|Evaluation|Assessment|Examine}: The {Laws|Legal guidelines} Of Parallel Circuits
In a parallel circuit {containing|that contains} two resistors and {powered|driven} by a battery, two electrical paths exist from the plus terminal of the battery to the minus terminal of the battery. {One|1|A single|One particular} electrical {path|route} goes {through|via|by means of|by way of} the {first|initial|1st|very first} resistor and the other electrical {path|route} goes {through|via|by means of|by way of} the {second|2nd} resistor.
{Here|Right here} are the {rules|guidelines} for {solving|fixing} {problems|issues|difficulties|troubles} in a parallel circuit:
{1|one}) The voltage drop across {each|every|every single|each and every} resistor equals the battery voltage.
{2|two}) The {total|complete} resistance in a parallel circuit {containing|that contains} two resistors is:
{1|one}/Rt = {1|one}/R1 + {1|one}/R2
{where|exactly where|in which|wherever}
Rt is the {total|complete} resistance
R1 is the {first|initial|1st|very first} resistor
R2 is the {second|2nd} resistor
{3|three}) The {total|complete} {current|present|existing|recent} is the sum of the currents {through|via|by means of|by way of} {each|every|every single|each and every} resistor. In a parallel circuit {containing|that contains} two resistors and {powered|driven} by a battery, there are two electrical paths from the {positive|constructive|good|optimistic} terminal of the battery to the {negative|damaging|unfavorable|adverse} terminal of the battery. The {current|present|existing|recent} splits: {Part|Component|Portion|Aspect} of the {current|present|existing|recent} {takes|requires|will take|can take} {one|1|a single|one particular} electrical {path|route} and {part|component|portion|aspect} of the {current|present|existing|recent} {takes|requires|will take|can take} the other electrical {path|route}.
{4|four}) The {total|complete} {power|energy|electrical power} dissipated is the sum of the {power|energy|electrical power} dissipated in {each|every|every single|each and every} resistor.
{5|five}) The voltage across any resistor equals the {current|present|existing|recent} {through|via|by means of|by way of} that resistor multiplied by the resistance of that resistor. {Since|Because|Given that|Considering that} {both|each|the two|equally} resistors are {directly|straight|immediately|right} across the battery, the voltage across {each|every|every single|each and every} resistor is the {same|exact same|identical|very same} as the battery voltage.
{6|six}) The {source|supply} voltage equals the {total|complete} {current|present|existing|recent} multiplied by the {total|complete} resistance.
The {Series|Sequence}-Parallel Circuit
Now let’s {examine|look at|study} the circuit of figure {one|1|a single|one particular}. In the figure, there is {one|1|a single|one particular} battery and {three|3} resistors.
{Look|Appear|Search|Seem} at resistor R1. There is only {one|1|a single|one particular} electrical {path|route} {through|via|by means of|by way of} R1. If we {remove|eliminate|get rid of|take away} R1, there is no electrical {path|route} from from the voltage {source|supply} to the junction marked Va. {Therefore|As a result|For that reason|Consequently}, R1 {must|should|need to|ought to} be in {series|sequence} with the other resistors in the circuit.
There are two electrical paths {between|in between|among|involving} Va and the minus {side|aspect|facet} of the voltage {source|supply}. {One|1|A single|One particular} electrical {path|route} goes {through|via|by means of|by way of} R2 and the other electrical {path|route} goes {through|via|by means of|by way of} R3. {Therefore|As a result|For that reason|Consequently} R2 {must|should|need to|ought to} be in parallel with R3.
R1 is in {series|sequence} with the parallel {combination|mixture|blend|mix} of R2 and R3.
The {current|present|existing|recent} flows {through|via|by means of|by way of} R1 and then splits. {Part|Component|Portion|Aspect} of the {current|present|existing|recent} flows {through|via|by means of|by way of} R2 and the other {part|component|portion|aspect} of the {current|present|existing|recent} flows {through|via|by means of|by way of} R3. {Hence|Therefore}, the {current|present|existing|recent} {through|via|by means of|by way of} R1 equals the sum of the currents {through|via|by means of|by way of} R2 and R3.
The voltage across R2 equals the voltage across R3 {because|simply because|due to the fact|since} R2 and R3 are in parallel. The battery voltage equals the voltage across R1 plus the voltage across the parallel {combination|mixture|blend|mix} of R2 and R3.
Nodal {Analysis|Evaluation}
In the circuit of figure {one|1|a single|one particular}, the algebraic sum of the currents {entering|getting into} the junction at Va is equal to zero. The junction at Va is {called|known as|referred to as|named} a node. {Hence|Therefore}, the {term|phrase|expression|time period} nodal {analysis|evaluation}.
The voltage V1 across the resistor R1 is equal to the voltage V of the {source|supply} minus the voltage Va.
The {current|present|existing|recent} I1 {through|via|by means of|by way of} R1 is equal to V1 divided by R1.
I1 = (V – Va)/R1
I2 is the {current|present|existing|recent} {through|via|by means of|by way of} the resistor R2.
I2 = Va/R2
I3 is the {current|present|existing|recent} {through|via|by means of|by way of} R3.
I3 = Va/R3
Assuming that I1 is {entering|getting into} the junction and I2 and I3 are leaving the junction we have the {following|subsequent} algebraic {formula|method|formulation|system}.
(V – Va)/R1 = Va/R2 + Va/R3
{Given|Provided|Offered} the {following|subsequent} values:
R1 = {10|ten} ohms
R2 = 20 ohms
R3 = 20 ohms
V = 20 volts
{Solve|Resolve|Remedy|Clear up} for the voltage Va
{Solve|Resolve|Remedy|Clear up} for the currents R2 and R3.
(V – Va)/R1 = Va/R2 + Va/R3
V/R1 – Va/R1 = Va/R2 + Va/R3
V/R1 = Va/R1 +Va/R2+ Va/R3
V = (Va/R1 + Va/R2 + Va/R3)*R1
V = Va*R1/R1 + Va*R1/R2 + Va*R1/R3
V = Va + Va*R1/R2 + Va*R1/R3
V = Va({1|one} + R1/R2 + R1/R3)
Va = V/({1|one} + R1/R2 + R1/R3)
Va = (20 volts)/({1|one} + {10|ten}/20 + {10|ten}/20)
Va = 20/{2|two} = {10|ten} volts
I2 = Va/R2 = {10|ten}/20 = {1|one}/{2|two} ampere
I3 = Va/R3 = {10|ten}/20 = {1|one}/{2|two} ampere
I1 = (V – Va)/R1 = (20 – {10|ten})/{10|ten} = {10|ten}/{10|ten} = {1|one} ampere
This concludes the explanation of nodal {analysis|evaluation}.
