Power is a measure of how quickly energy is transferred and it’s measured in Watts. The more energy that is transferred in a certain time, the greater the power. A 100 W light bulb transfers more electrical energy each second than a 60 W light bulb.

You can work out power using a simple equation. Power is the amount of energy transferred in joules over the time taken in seconds. For example an electric lamp transfers 500J in 5s. Its power is 100W.

You can also calculate the power of an electrical appliance by knowing the current that flows through it and the potential difference across it. You simply multiply the current in Amps by the Potential difference in Volts. For example, in this diagram: what is the power of 5A, 1.5 V electric heater, well that’s simply 7.5W.

Fuses play an important role in making sure our appliances don’t fry when a surge of electricity flows through them. By rearranging the equation P=IV we can work out the best fuse to use. For example what current flows through a 1.15kW electric fire with a voltage of 230V? Well that’s 5 amps. Seeing as fuses usually come in the standard ratings of 3A, 5A and 13A, the best option here would be the 13A as the other ones would blow without a surge at all.

A fuse that keeps on blowing is an active problem and can be difficult to find. However if you use these steps, you should be able to locate and repair it.
