What is electromotive force of a cell?

What is electrostatic force?

What is electromagnetic force?

The equation of electromotive force for an electric circuit contianing resistance and self inductance is E=Ri+L(di)/(dt) , where E is the electromotive force given to the circuit, R, the resistance and L, the coefficient of induction. Find the current 'i' at time t when E= 0

What is conservative force?

A battery is used to charge a parallel plate capacitor till the potential differece between the plates becomes equal to the electromotive force of the battery. The ratio of the energy stored in the capacitor and the work done by the battery will be
