Initial parallel configuration (Circuit 1) and final series configuration (Circuit 2).
Initial parallel configuration (Circuit 1) and final series configuration (Circuit 2).
Two identical resistors, each of resistance \(R\), are initially connected in parallel across an ideal battery of fixed electromotive force \(\varepsilon\). The circuit is then reconfigured so that the same two resistors are connected in series across the same battery. Which of the following claims correctly describes the change in the total rate of energy dissipation by the two resistors, along with the valid justification?
