Physics

A circuit is constructed with four resistors, one inductor, onebattery and a switch as shown. The values for the resistors are:R1 = R2 = 56 Ω, R3 = 45 Ω andR4 = 91 Ω. The inductance is L = 255 mH and the batteryvoltage is V = 24 V.

1)

The switch has been open for a long time when at time t = 0, theswitch is closed. What is I1(0), the magnitude of thecurrent through the resistor R1 just after the switch isclosed?

_______A

2)

What is I1(∞), the magnitude of the current thatflows through the resistor R1 a very long time after theswitch has been closed?

_______A

3)

What is VL(0), the magnitude of the voltage acrossthe inductor just after the switch is closed?

______V

4)

What is IL(∞), the magnitude of the current throughthe inductor after the switch has been closed for a very longtime?

___________A

5)

What is I2(0), the magnitude of the current throughthe resistor R2 just after the switch is closed?

_______________A
