Using Kirchhoff's rules, find the following. (E1 = 70.4 V, E2 = 61.8 V, and E3 = 78.4 V.) (a) the current in each resistor shown in the figure above (Enter the magnitude.) IR1 = mAIR2 = mAIR3 = mA (b) the potential difference between points c and f magnitude of potential difference V point at higher potential
