Question

In the circuit shown, A and B are equal resistances. When S is closed, capacitor C charges from an ideal cell E and the circuit reaches steady state. Which statements are correct?

G1 Physics · Accepted Answer

In steady state the capacitor branch is open. Equal resistors A and B form a divider, so capacitor voltage is E/2 and U=½C(E/2)²=CE²/8, making D true and C false. The current/energy balance during charging gives more heat in A; at steady state equal current in equal A and B gives equal power. Correct: A, B, D.
