For the RL circuits a simple RL circuit let the inductance be 3.0H, the resistance 7.50 and the battery emf at 36v. At t=0 the switch is closed.
1.Calculate the voltage across the inductor at when the current is 2.00A.
2.Calculate the time at which the current is 0. 3.Calculate the time at which the current is 1.
4.Calculate the current when t=0.4s
5. After a very long time what is the voltage across the Inductor.
