A step-down transformer is an electrical device that transforms voltage from a high level to a low level. It is also known as a voltage transformer. The transformer consists of two or more coils of wire wrapped around a common iron core. The primary coil has more turns of wire than the secondary coil. The transformer uses the principle of electromagnetic induction to change the voltage. The primary coil creates a magnetic field when an electric current flows through it. The secondary coil is placed in the magnetic field. This induces a current in the secondary coil. The voltage in the secondary coil is lower than the voltage in the primary coil because the secondary coil has fewer turns of wire.
