Circuit schematic with three resistors.
A circuit consists of an ideal battery of potential difference \(\Delta V\) connected to three resistors. Resistor 1 has resistance \(R_1 = R\), while Resistors 2 and 3 have resistances \(R_2 = 2R\) and \(R_3 = 6R\), respectively. Resistors 2 and 3 are connected in parallel with each other, and this parallel combination is connected in series with Resistor 1 across the battery. Which of the following correctly ranks the rate of energy dissipation \(P_1\), \(P_2\), and \(P_3\) in Resistors 1, 2, and 3, respectively?
