An RL series circuit has the following components: 5.0-mH coil, 4.8-$\Omega$ resistor, 12-V battery, ammeter, and switch. After the switch is closed for a long time, find the final value of the current.

Question

Quizplus · Accepted Answer

The final current in an RL circuit is determined by Ohm's Law: I = V/R. Here, V = 12 V and R = 4.8 Ω, so I = 12 V / 4.8 Ω = 2.5 A.
