Resistor ladder circuit connected to an ideal battery.
Resistor ladder circuit connected to an ideal battery.
An ideal battery of potential difference \(\varepsilon\) is connected to a network of four identical resistors, each of resistance \(R\). Resistor \(R_1\) connects the positive terminal of the battery to node \(B\), and resistor \(R_2\) is connected between node \(B\) and the grounded negative terminal. Resistor \(R_3\) connects node \(B\) to node \(C\), and resistor \(R_4\) connects node \(C\) to the grounded negative terminal. What is the electric potential \(V_B\) at node \(B\) relative to the grounded negative terminal?
