In each of the circuits shown, calculate the current through each resistor and potential difference across each resistor.
For first circuit
Applying Kirchoffs Law
=> 20 - 10 = (I1 + I2 ) * 10 + 10 * I1 + 20 * I1
Also, 20 - 10 = (I1 + I2 ) * 10 + 15 * I2
=> I1 = 0.166 A
=> I2 = 0.33 A
=> current through R1 = 0.496 A Potential difference = 4.96 V
=> current through R2 = 0.33 A Potential difference = 4.95 V
=> current through R3 = 0.166 A Potential difference = 1.66 V
=> current through R4 = 0.166 A Potential difference = 3.32 V
For second circuit
Applying Kirchoffs Law
=> 20 = (I1 + I2 ) * 20 + 15 * I2 + 10 * I2
Also, 20 - 10 = (I1 + I2 ) * 20 + 10 * I1
=> I1 = 0.0526 A
=> I2 = 0.421 A
=> current through R1 = 0.0526 A Potential difference = 0.526 V
=> current through R2 = 0.421 A Potential difference = 6.315 V
=> current through R3 = 0.421 A Potential difference = 4.21 V
=> current through R4 = 0.4736 A Potential difference = 9.472 V
For third circuit
Applying Kirchoffs Law
=> 20 = (I1 + I2 ) * 20 + 15 * I2 + 10 * I2
Also, 20 - 10 = (I1 + I2 ) * 20 + 10 * I1
=> I1 = 0.0526 A
=> I2 = 0.421 A
=> current through R1 = 0.0526 A Potential difference = 0.526 V
=> current through R2 = 0.421 A Potential difference = 6.315 V
=> current through R3 = 0.421 A Potential difference = 4.21 V
=> current through R4 = 0.4736 A Potential difference = 9.472 V
