**Voltage:**The potential difference between two points. Is measured in Volts (V) and has the symbol ‘V’.

**Current:**The flow of electrons in a circuit. Is measured in Amps (A)and has the symbol ‘I’.

**Resistance:**A material’s opposition to an electrical current. Is measured in Ohms (Ω) and has the symbol ‘R’.

**Power:**The rate of doing work. Is measured in Watts and has thesymbol ‘P’.

**Energy:**The capacity for work, the product of power and time. Has the symbol ‘E’. The basic unit of energy is the Joule, but electrical energy is normally expressed in Watt hours (Wh) or kilo Watt hours (kWh). One kWh is 1000 Wh.

The relationship between these units is:
