See the transformer equation. These devices convert voltage from high to low or vice-versa which makes transporting and using it so much easier.

Transformers change the voltage of an alternating current (ac) electrical supply.Some times transformers make the output voltage bigger than the input voltage, this is a Some times transformers make the output voltage smaller than the input voltage, this is a The changing magnetic field induces a potential difference (voltage) in the We can work out the transformer output voltage if we know the input voltage and the number of turns (coils) on the primary and secondary coils, using the equation below;Transformers are very efficient devices, if we assume they are 100% efficient (no energy wasted), then the electrical input teganwoodhouse23. A transformer is a very useful device in the electrical grid. | All Rights Reserved The output voltage of a transformer depends on the number of turns on each of the coils as well as the input voltage:input (primary) voltage / output (secondary) voltage = primary turns / secondary turns(The ratio of the voltages is equal to the ratio of the number of turns).The individual loops of wire going around each side of the transformer should be referred to as We use cookies to ensure that we give you the best experience on our website.
