A `1 -k Omega` resistor is connected in series with a `10-mH` inductor, a `30 V` battery and an open switch. At time `t= 0`, the switch is suddenly closed.
a. What is the maximum current in this circuit and when does it occur?
b. What are the voltage drops across the inductor and across the resistor `20 mu s` after the switch is closed?
c. On a single set of axes, sketch the voltage across the resistor and the voltage across the inductor as functions of time. Also, sketch a graph of the current in the circuit as a function of time.

A

the power being supplied by the battery is `20.0 W`

B

the power being delivered to the resistor is `20.0 W`

C

the power being delivered t the inductor zero

D

the energy stored in the magnetic filed of the indicator is `20.0 J`
