Circuit network of four identical resistors connected to an ideal battery.
Circuit network of four identical resistors connected to an ideal battery.
Four identical resistors, labeled \(R_1\), \(R_2\), \(R_3\), and \(R_4\), each having resistance \(R\), are connected to an ideal battery of potential difference \(\varepsilon\) as shown in the circuit diagram. Resistor \(R_1\) is connected in series with the battery, followed by a junction that splits into two parallel branches: one branch contains only resistor \(R_2\), and the other branch contains resistors \(R_3\) and \(R_4\) in series. Which of the following correctly ranks the rate of thermal energy dissipation \(P_1\), \(P_2\), \(P_3\), and \(P_4\) in the four resistors?
