Simple Description

A type of transformer that INCREASES voltage

Further Detail

Step up tranformers have more coils on the secondary coil then they do on the primary coil. They increase the voltage by the same factor as the number of turns increaes by. For example, if a step up transformer has twice as many turns on its secondary coil compared to its primary coil then it will double the voltage. The formula for calculating the increase in voltage is:
