The amount of electricity which is flowing (it is called the current) is measured in units called amps. The pressure of electricity, the voltage, is measured in volts. A unit of resistance is called an ohm.
Current, voltage and resistance have definite relationship to one another. The current and the voltage determine the power, the rate at which electrical energy is used. A unit of power is a watt.

In System International (SI) there are seven base units. They are the following:
- the metre (m) as the unit of length;
- the kilogram (kg) as the unit of mass;
- the second (s) as the unit of time;
- the ampere (A) as the unit of electric current;
- the kelvin (K) as the unit of (thermodynamic) temperature difference;
- the mole (mol) as the unit of substance;
- the candela (cd) as the unit of luminous intensity.
All other SI units are derived from the seven base units. They are the joule, the watt, the pascal, the newton and, most interestingly, the unit of charge, the coulomb.
