1. The switch in the image had been in position (a) for a long time. The switch is moved to position (b) at time t = 0. The graph shows the current through the resistor as a function of time for four different combinations of resistance and inductance. Assume that R = 4 and L = 2 mH. (a) Match each plot in the graph to the correct value of R and L. 2R and 2L: R and 2L: a S b 2R and L: R and L: E = I 4A. (b) What is the emf of the battery? Show your work. 2A- d b t www R 2. The switch in the circuit has been open for a long time, then closes at time t = 0. (a) What is the current in each resistor immediately after the switch closes? 14 = 16 = 652 ww eeeee 10mH eeee (b) What is the current in each resistor a long time after the switch closes? 452 142 = 8V 160 = (b) What is the current in each resistor immediately after the switch reopens? 142 = 16 =
