In which way you can establish an instantaneous displacement current of 1.0 A in the space between the parallel plates of 1 `mu`f capacitor?

Text Solution

Verified by Experts

Given: Displacement current.
`I_(d) = epsilon_(0) (d phi_(E ))/(dt)`
= `epsilon_(0) (d(EA))/(dt )" "(therefore phi_(E ) =EA)`
`I_(d) = epsilon_(0)A (d)/(dt) ((V)/(d)) " "(because E = ((V)/(d)))`
`I_(d) = (epsilon_(0)A)/(d) ((dV)/(dt)) " " (because C = (epsilon_(0)A)/(d) )`
Formula :
`I_(d) = C . (dV)/(dt)`
Solution:
`(dV)/(dt) = (I_(d))/(C) = (1.0)/(1 xx 10^(-6)) = 10^(6) `
