a transformer is a device that is used to increase or decrease voltage. it consists of 2 coils primary and secondary and is based on the principle of mutual induction.
when the secondary coil has less no. of turns than the primary coils the tranformer decreases the voltage and that is called a step down transformer and when it has more no. of turns than the primary coil then it increases the voltage and its called a step up transformer.
