In a purely capacitive ac circuit, we get,
Im = Vm*ω*C, ...(1)
Where, Im = Amplitude of the current
Vm = Amplitude of the voltage
Now, what I think is,
We know that in a purely capacitive circuit, voltage lags behind current by a phase difference of ∏/2 rad. So, at any time 't',
I = Im...
In a closed loop when we apply an applied force on an object the object starts at point A and stops at point A.
