Power System Volts and amperes are measures of electricity. A volt is the unit of electric potential difference, or the size of the force that sends the electrons through a circuit. An ampere is the unit used to measure electric current. Current is a count of the number of electrons flowing through a circuit. One amp is the amount of current produced by a force of one volt acting through the resistance of one ohm. (An ohm is a way of measuring resistance.

What is 'Bulb Voltage'? What is 'Bulb Voltage'? A volt is a unit of measure that determines the amount of electrical pressure an electronic object uses. Volts push the electrical current through the conductor to create power. Therefore, the relationship between voltage, current, and power is this: Power (measured in watts) = Current (measured in amps) x Voltage (measured in volts). There are two types of currents that can be pushed through electrical devices.
