Pressure
== == Volts are a measure of electrical "pressure" differential.
Volts are the measure of Eletro motive force. (EMF)
There are different units for electricity, depending on what you want to measure; for example: volts to measure voltage amperes to measure current watts to measure power etc.
Volts are the measure of electrical force or pressure that causes current to flow in a circuit. This is related directly to electricity. Voltage is also measured in volts.
American use both watts and volts to measure units of electricity.
The watt is the unit of power. For electricity, watts = volts x amps.
Volts, amperes, watts and ohms. pressure (or force), current, energy, and resistance.
The measure of potential energy in electricity is called voltage. Voltage is the potential difference in electric charge between two points in a circuit, and it is measured in volts (V).
The watt is the unit of power. For electricity, watts = volts x amps.
Volts, amperes, watts and ohms. pressure (or force), current, energy, and resistance.
Because they are different characteristics. If you'd compare electricity to water, Volts would be the pressure, and Amps would be the flow. So you can have high pressure but little flow - like a water pistol. Or you can have high flow and little pressure - like upending a bucket.
220 volts means the power behind the electricity. current means the speed at which the electricity is being transmitted. currecnt is measure in amperes.
