Circuit schematic before resistor R_D burns out.
Circuit schematic before resistor R_D burns out.
A circuit contains an ideal battery of voltage \(V_0\) connected in series with resistor \(R_A\). Downstream of \(R_A\), the circuit splits into two parallel branches: Branch 1 contains resistor \(R_B\), and Branch 2 contains resistors \(R_C\) and \(R_D\) in series. Resistor \(R_D\) suddenly burns out and becomes an open circuit. Which of the following claims correctly describes the change in power dissipated by resistor \(R_B\) and provides the correct physical justification?
