Question

In the shown circuit, the ideal cell has emf 15 V and every resistor is 3 Ω. After a long time, the potential difference across the 3 μF capacitor is:

G1 Physics · Accepted Answer

At steady state the capacitor carries no current and acts as an open circuit. Solve the remaining resistor network by nodal division; the two capacitor terminals settle at potentials differing by 12 V. Correct answer: C.
