Question
When the key K is passed at t =t0, Which of the following statements about the current I in the resister AB of the given circuit is ture?
Options
A.I = 2 mA at all t
B.I oscillates between l mA and 2 mA
C.I = l mA at all t
D.Att = 0,I = 2mA and with time it goes to l mA
Solution
At time i = 0 i.e., when the capacitor is charging, then current through the circuit,
I =
= 2mA
When capacitor is fully charged, no current will pass through it.
Hence current through the circit
I =
= 1mA
I =
= 2mAWhen capacitor is fully charged, no current will pass through it.
Hence current through the circit
I =
= 1mACreate a free account to view solution
