The value of displacement current at `t=1` time constant is

A

`(120)/(e)`

B

`(120)/(e^(2))`

C

120 mA

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
For continuity dispalcement current should be equal to conduction current
`q=q_(0)(1-e^(-t//RC))implies|i|=(q_(0))/(RC)e^(-t//RC)CR=t`
`implies(1200muF)/(ex1)impliesi=(0.0012)/(e)A=(1.2)/(e)mA`

Define displacement current. What role does it play while charging a capacitor by de source? Is the value of displacement current same as that of the conduction current? Explain.

A : When the frequency of the AC is increased, the displacement current increases. R : The sum of the conduction current and displacement current is constant.

Assertion : Displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor does not charge Reason : The displacement current arises in the region in which the electric field is constant with time.
