It needs a ‘push’, or energy, to keep itmoving. We call this energy the voltage of thecircuit. 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 aconductor such as a trip of metal or a wire – andthe current following through it always vary inthe same proportion. So if you double thevoltage, you double the current. This is incrediblyuseful; because it lets you predict the currentyou will get for a particular voltage.• The thickness of silk is measured in what-Denier• Ohm’s law does not apply to semiconductorsand conductors when there is change intemperature.• In our houses we get 220 V a.c.
