### Class subject: Electric Potential.

 The electric potential also called voltage is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field. This value can be calculated in either a static or a dynamic electric field at a specific time in units of joules per coulomb or volts (V). The electric potential at infinity is assumed to be zero. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance.

This fun physics game may answer the following questions:
• Which is the lowest electrical potential?
• Which is the highest electrical potential?
• What is the electrical potential difference of objects?
