Question

A capacitor is connected in the circuit shown with two resistors, A and B. Resistor A has a resistance of 2R, while resistor B has a resistance of R The emf of the battery, which has negligible internal resistance, is 12.0 V. Immediately after the switch is closed, the capacitor has a potential difference of 6.00 V, with the top plate having a higher potential C Immediately after the switch is closed, the current through resistor A is 3.00 A. At that instant in time, calculate the magnitude of the current in the branch of the circuit that has the capacitor in it -2 Submit Answer Save Progress

Explanation / Answer

When switch is closed current through 2R is 3A and is given that potential across capacitor is 6 volt

Hence potential through R is also 6 volt as they are in parallel.

Voltage across 2R is 6 Vand current is 3 Amp then value of R is 1ohm.

Current through R = 6/ 1 Amp

Hence current through 2R is 3 Amp

Then current through capacitor is -3 amp
