The ideal battery in Figure (a) has emf 8 -6.2 V. Plot 1 in Figure (b) gives the electric potential difference V that can appear across resistor 1 of the circuit versus the current i in that resistor. The scale of the Vaxis is set by V, - 18.9 V, and the scale of the i axis is set by i, 3.21 mA. Plots 2 and 3 are similar plots for resistors 2 and 3, respectively. What is the current in resistor 2? SK Number (a) Units (mA) (4)

Four resistors are connected to a battery as shown in the R, = 2R figure. The current through the battery is I, the battery's electromotive force (emf) is E = 6.10 V, and the resistor values are R1 = R, R, = 2R, R3 = 4R, and R4 = 3R. Find R, = R the voltages across each resistor. R = 3R V = V V½ = R, = 4R V3 = V V4 = V
