You are given a `2 mu F` parallel plate capacitor. How would you establish an instantaneous displacement current of 1mA in the space between its plates ?

Text Solution

Verified by Experts

Charge on plate,
q = CV
`I_(d)dt=CdV`
`therefore I_(d)=C(dV)/(dt)`
`therefore (dV)/(dt)=(I_(d))/(C )=(10^(-3))/(2xx10^(-6))`
`therefore (dV)/(dt)=500(V)/(s)`
By applying variable p.d. of `500(V)/(s)` we can obtain displacement current of desired value.
