Circuit with a single resistor (Circuit 1) and with two parallel resistors (Circuit 2).
Circuit with a single resistor (Circuit 1) and with two parallel resistors (Circuit 2).
A circuit initially consists of an ideal battery of potential difference \(\Delta V\) connected to a single resistor of resistance \(R\). An identical resistor is then connected in parallel with the first resistor, and measurements confirm that the total rate of electrical energy dissipated by the circuit doubles. Which of the following statements provides the correct physical explanation for this observation?
