How does a step down transformer work?
Step-down transformers reduce a higher voltage to a lower voltage for use in different types of equipment. Power companies use them to reduce the voltage in power lines so it can be used in your home.ConceptAt its simplest, a step-down transformer uses two coils of wire–the primary and secondary coils–wrapped around a common core, which is typically made of iron.Voltage InA high voltage is applied to the primary coil of the transformer, creating an electromagnetic field in the coil.InductionThe field created by the primary coil is passed through the common core to the secondary coil, where it causes another electromagnetic field to be created (or induced) in that coil. This process is called induction.Voltage OutThe induced field causes a voltage to flow in the secondary coil. This voltage is then used for other purposes.Proportional OutputThe voltage drop from the primary coil to the secondary coil is directly proportional to the number of wire turns in the two coils. The formula is
