## Define electromotive force, Physics

Assignment Help:

Electromotive force EMF (ξ) - This is the electrical energy from an ideal battery with no internal resistance.  It is also the open circuit value of a battery (no current is drawn).  EMF voltage represented by ξ. It is also explained as the work required by a battery to move positive charge around a circuit. #### Kinematics, how to solve question for kinematics problem
