When the key E is pressed at time t = 0,...

When the key `E` is pressed at time `t = 0`, which of the following statements about the current `I` in the resistor `AB` of the given circuit is true.

A

`I = 2 mA` at all `t`

B

`I` oscillates between `1 mA` and `2 mA`

C

`I = 1 mA` at all `t`

D

At `t = 0, I = 2 mA` and with time it goes to `1 mA`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) At time `t = 0` i.e., when capacitor is charging current `i= (2)/(1000) = 2 mA`
When capacitor is full charged, no current will pass through it, hence current through the circuit
`i= (2)/(2000) = 1 mA`
