Question

The switch in the circuit shown in the figure has been open for a long time. The resistors in the circuit each have a value of 60 ?, the inductors each have a value of 270 mH, and V = 10 V. (a) What is the total equivalent inductance of the circuit between points A and B? (b) What is the current through R1 the instant after the switch is closed? (c) What is the current through R1 long after the switch has been closed?

The figure shows R1 as a resistor in parallel, R2 is a resistor in series. L1 is an inductor in parallel and L2 and L3 are inductors in series.

Explanation / Answer

Please provide the figure b/c without that it couldn't be determined that whether or not circuit has a series combination.
