A parallel plate capacitor has circular plates, each of radius `5.0 cm.` It is being charged so that electric field in the gap between its plates rises steadily at the rate of `10^(12) "Vm"^(-1)"s"^(-1).`What is the displacement current?

Text Solution

Verified by Experts

`I_(0)=epsilon_(0)(dphi_(epsilon))/(dt)=epsilon_(0)pir^(2)(dE)/(dt)=8.85xx10^(-12)xxpixx(5xx10^(-2))xx10^(12)=0.07A`.
