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 Î©, R₃ = 45 Î© andR₄ = 91 Î©. 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(âˆž), the magnitude of the current thatflows through the resistor R₁ a very long time after theswitch has been closed?
_A
3)
What is V_L(0), the magnitude of the voltage acrossthe inductor just after the switch is closed?
______V
4)
What is I_L(âˆž), 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
