Physics

An inductor (0.2 Henry) and a resistor (2ohms) are connected inseries with a battery of EMF 5.0 volts.

a) Draw the circuit (don't forget the switch)

b) At time t=0 and time= infinity find the current that passesthrough the battery

c) What's the time constant for the circuit?

d) What's the back EMF provided by the inductor at t= 1.0sec?

e) What's instantaneous energy saved in the inductor at time t=1.0 sec?

f) What is the total magnetic flux that is coupled with theinductor at t= 1.0 sec?
