Force between the plates of a capacitor
WebDec 12, 2024 · In a small time interval dt, a positive charge dq=I*dt will be deposited on one plate of capacitor, which will attract same amount of negative charge on the other plate and hence establish an electric field between them. The electric field of battery doesn't do any work initially since the capacitor is uncharged in the beginning.
