What is i1 just after the switch is closed?

What is i2 just after the switch is closed?

What is the the potential difference across R2 just after the switch is closed?

What is the the potential difference across L just after the switch is closed?

What is i1 a long time after the switch is closed?

What is i2 a long time after the switch is closed?

What is the the potential difference across L a long time after the switch is closed?

What is the value of the current in the switch a long time after the switch is closed?

What is the the potential difference across R2 a long time after the switch is closed?

Given,

= 95.0 V, R1 = 60 , R2 = 120.0 , and L = 35 H

(a) i1 = /R1 = 95/60 = 1.58 A

b)i2 = 0 since just after closing the switch the current thorugh the inductor is zero.

c)Current iS = i1 = 1.58 A

d)v2 = i2 R2 = 0 x 13 = 0

e)VL = = 95 Volts

f)Since the resistors are in parallel combination the voltage across them will be same.

i1 = /R1 = 95/60 = 1.58 A

g)i2 = /R2 = 95/120 = 0.792 A

h)iS = i1 + i2 = 1.58 + 0.792 = 2.37 A(switch current)

i)V2 = i2R2 = 0.792 x 120 = 95.04 Volts (potential across R2)

k)VL = 0 long time after switch is closed.(potential across inductor)
