Question
In the circuit shown in the figure (Figure 1) , the battery and the inductor have no appreciable internal resistance and there is no current in the circuit. Assume that R = 15.0%u03A9 and L = 12.0mH
Part A
Immediately after the switch is closed, find the reading of the ammeter A .
Part B
Immediately after the switch is closed, find the readings of the voltmeters (V1 and V2) .
Separate your answer with a comma.
Part C
Find the reading of the ammeter A after the switch has been closed for a very long time.
Part D
Find the readings of the voltmeters (V1 and V2) after the switch has been closed for a very long time.
Separate your answer with a comma.
Explanation / Answer
a)immediately after switch is closed inductor acts as open circuit ,so
I=0 A
b)
V1=0V amd V2=25 V
c)
after long time inductor acts as short circuit
so ,I=V/R =25/15 =1.67 A
d)
V1=25 V and V2=0
