Explanation:


A transformer is an electrical device that is used to change the voltage level of an alternating current (AC) electrical power supply. It works on the principle of electromagnetic induction, which basically means that it uses a magnetic field to convert electrical energy from one circuit to another. The transformer has two coils of wire, one primary coil, and one secondary coil. The primary coil is connected to the power source, and the secondary coil is connected to the load. When an AC voltage is applied to the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. This voltage is proportional to the ratio of the number of turns in the primary and secondary coils.

Transforms Voltage:


The primary function of a transformer is to transform voltage. The voltage in the secondary coil is dependent on the ratio of the number of turns in the primary and secondary coils. If the number of turns in the secondary coil is greater than the number of turns in the primary coil, the voltage in the secondary coil will be higher than the voltage in the primary coil. If the number of turns in the secondary coil is less than the number of turns in the primary coil, the voltage in the secondary coil will be lower than the voltage in the primary coil. Transformers are used to step up or step down the voltage level of an AC power supply.

Transforms Current:


A transformer also transforms current. The current in the secondary coil is dependent on the ratio of the number of turns in the primary and secondary coils. If the number of turns in the secondary coil is greater than the number of turns in the primary coil, the current in the secondary coil will be lower than the current in the primary coil. If the number of turns in the secondary coil is less than the number of turns in the primary coil, the current in the secondary coil will be higher than the current in the primary coil.

Transforms Power:


A transformer does not transform power. The power in the primary coil is equal to the power in the secondary coil. However, the transformer can either step up or step down the voltage level, which can affect the power delivered to the load. If the voltage is stepped up, the current will be stepped down, and if the voltage is stepped down, the current will be stepped up. The power delivered to the load will be the same as the power supplied to the primary coil.

A transformer mainly transforms Power. For Step Up transformer voltage increases and current decreases and in case of Step Down transformer voltage decreases and current increases.
