Potential Energy

Electrical Potential Energy & Electrical Potential There are 3 charges (1 C each). In this example, the amount of work done by the person is 30 J. Thus, electrical potential energy = 30 J. U = 30 J Electrical potential =30/3 = 10 J/C or 10 V V = 10 V

Electrical Potential Every Couloumb of charge that moves from one side of the battery to the other side has done 1.5 J of work. V = U/q =1.5 J/1 C =1.5 J/C or 1.5 V
