An a.c. source with variable frequency is connected to a parallel plate capacitor . How will the displacement current be affected with the decrease in frequency of the source ?

Text Solution

Verified by Experts

Displacement current decreases with decrease in frequency of a.c. source)
[Hint : `I_(D)=in_(0)(dphi_(epsilon))/(dt)=in_(0)(d)/(dt)(EA)=in_(0)(d)/(dt)(V/d.A)`
`=(in_0A)/(d).(dV)/(dt)=C(dV)/(dt)=C(d)/(dt)(V_(m)sinomegat)=CV_(m)omegacosomegat" Thus"I_Dpropomega`]
