HOW DOES AN ELECTRICAL TRANSFORMER WORK?
 

Lots of electrically powered machines have transformers in them, but how do they transform the electricity?

An electrical transformer changes the voltage of the electricity. It can only work using AC (alternating current). It transforms electricity at one voltage into electricity at another voltage.

Household gadgets need electrical transformers because the mains electricity comes in at 240 Volts; that's enough to kill you. And what's more the electronic circuits that most modern machines use would burn up in an instant if they were connected to electricity at this voltage.

To do its magic on the high voltage and change it to low voltage the electrical transformer uses two rather intriguing and important phenomena. Firstly whenever an electric current flows, there is magnetism around it. Secondly whenever a magnetic field changes (by moving or by changing strength) a voltage is made. If there's a wire close by when this happens then a current will flow in the wire as the magnetism changes.
The electrical transformer takes in high voltage electricity and lets it run through lots of coils wound around an iron core. Because the current is alternating the magnetism in the core is also alternating. Also round the core is an output wire with less coils. The changing magnetism generates a current in the wire and less coils means less voltage. So the voltage is 'stepped-down'.

You can do it all the other way to 'step-up' the voltage with more coils on the output than on the input. Huge dangerously high voltages are generated by such step-up electrical transformers at power stations.

Unfortunately this transformation takes some energy so you get slightly less energy out of the transformer than you put in, but the loss is usually only small.

A transformer uses an input current to make a changing magnetic field in an iron core. This changing field is used to generate a voltage in the output coil. Each turn on the input coil generates a unit of magnetic field in the iron core and each turn on the output coil traps a unit of magnetic field. So, for example, if there are 100 loops on the input coil, the magnetic field in the core will be 100 times as strong as if there were only one coil.

Each lot of 100 loops generates the same voltage. If there are 10 lots of 100 loops stacked end to end, the voltages add up. The output voltage is 10 times the input voltage. Voila extra voltage! To make up for the extra voltage, there is a proportional drop in current
