BeginnerMCQConceptual22.4k
A schematic diagram showing a DC circuit. On the left side, a vertical battery labeled Delta V with a switch S in series on the top wire. The wire splits into two parallel vertical branches to the right. The middle branch labeled Branch 1 contains a single resistor R. The rightmost branch labeled Branch 2 contains a resistor R in series with a parallel-plate capacitor C. No other components, labels, or annotations appear.
Circuit schematic containing two parallel branches and a switch.
A circuit contains an ideal battery of potential difference \(\Delta V\), an open switch \(S\), and two parallel branches. Branch 1 contains a resistor of resistance \(R\). Branch 2 contains a resistor of resistance \(R\) connected in series with an initially uncharged capacitor of capacitance \(C\). Switch \(S\) is closed at time \(t = 0\). Which of the following claims and justifications correctly describes the current in Branch 2 a long time after the switch is closed?
