A transformer is a device for increasing or decreasing voltage through electromagnetic induction. It is very used in power transmission where alternating currents can be stepped up or down for house hold usage.
Electromagnetic induction is the process of generating current through magnetic fields.
It is made up of primary and secondary coils which helps to change voltage in the presence of magnetic filed at the core.
A transformer can either be a step up or step down device.
