Circuit diagram containing four identical resistors and an ideal battery.
Circuit diagram containing four identical resistors and an ideal battery.
An ideal battery of potential difference \(\varepsilon\) is connected in a circuit with four identical resistors, each of resistance \(R\), labeled \(R_1\), \(R_2\), \(R_3\), and \(R_4\). Resistor \(R_1\) is located in the main branch adjacent to the battery, after which the circuit splits into two parallel branches. One parallel branch contains resistor \(R_2\), and the other parallel branch contains resistors \(R_3\) and \(R_4\) connected in series with each other. Which of the following correctly ranks the magnitude of the electric current \(I\) through each resistor?
