Potential Electrical Energy Why is it safe to touch a 1.5 volt battery at both ends but it is not safe to touch two wires sticking out of a 120 volt outlet. In both cases, you are completing a circuit. But in the case of the 1.5 volt battery, the amount of energy each electron has is much less than that of the electrons leaving the outlet. The amount of potential energy is higher in the 120 volt outlet.

Potential Electrical Energy The potential energy of a power source is very important to consider. The greater the potential energy of a power source, the greater the force applied to the electrical load in the circuit. This is why a 1.5 volt battery will not light a 60 watt bulb. The electrons leaving the battery do not have enough energy to create light

Potential Electrical Energy The energy each electron has is called the electric potential of the electron. Electric potential is commonly called voltage. The common unit of measurement of electric potential is the volt. The symbol of the volt is V.
