Resistance was discovered by Girge Ohm in 1826, and is measured in ohms.
Electricity does not flow through a circuit by itself. It needs a ‘push’, or energy, to keep it moving. We call this energy the voltage of the circuit. Voltage is measured in volts (v).
The German scientist George Ohm (1787-1854) is best remembered for working out ohm’s law. He discovered that they voltage across a conductor such as a trip of metal or a wire – and the current following through it always vary in the same proportion. So if you double the voltage, you double the current. This is incredibly useful; because it lets you predict the current you will get for a particular voltage.
