Answer #1

SOLUTION;-

GIVEN DATA;-

The switch in the figure is closed at t=0 when the current I is zero.When I = 15 mA,what is the potencial difference across the inductor ?

THE GIVEN ;;

When I = 15 OmA,

the drop across the resistor is V = I x R = 15 x 10^-3 A x 4 x 10^3 Ohms = 60V.

The voltage left is across the inductor and is V = 240 - 60 = 180 V.
