Question

A circuit is constructed with four resistors, one inductor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 54.0 ?, R3 = 83.0 ? and R4 = 110.0 ?. The inductance is L = 355.0 mH and the battery voltage is V = 24.0 V.

A circuit is constructed with four resistors, one inductor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 54.0 ?, R3 = 83.0 ? and R4 = 110.0 ?. The inductance is L = 355.0 mH and the battery voltage is V = 24.0 V. 1) The switch has been open for a long time when at time t = 0, the switch is closed. What is I1(0), the magnitude of the current through the resistor R1just after the switch is closed? 2) What is I1(?), the magnitude of the current that flows through the resistor R1a very long time after the switch has been closed? 3) What is VL(0), the magnitude of the voltage across the inductor just after the switch is closed? 4) What is IL(?), the magnitude of the current through the inductor after the switch has been closed for a very long time? 5) What is I2(0), the magnitude of the current through the resistor R2just after the switch is closed?
