In a circuit, a parallel combination of a resistor R2 = 17.1 Ω and an inductor of L = 6.80 mH is connected in series with a resistor of R1 = 5.90 Ω, a 6.00-V dc battery, and a switch. What is the voltage across the 5.90-Ω resistor after the switch has been closed for a long time? At this terminal velocity, what is the power dissipated in the resistor? What is the terminal velocity of the rod?
