Circuit diagram with battery V_0, bulbs A, B, and C, and switch S.
In the circuit shown, three identical lightbulbs labeled \(A\), \(B\), and \(C\), each of resistance \(R\), are connected to an ideal battery of potential difference \(V_0\). Switch \(S\) is initially open. Switch \(S\) is then closed. Which choice correctly describes the change in brightness (power dissipated) of bulbs \(A\) and \(B\) after switch \(S\) is closed, and correctly ranks the power dissipated by all three bulbs in this final state?
