Can A Transformer Increase Voltage

Can A Transformer Increase Voltage？

Yes, a transformer can increase voltage. This is achieved through the use of two coils of wire, one with a greater number of turns than the other. When an alternating current is applied to the primary coil (with the lower number of turns), it generates a magnetic field that induces a voltage in the secondary coil (with the higher number of turns). The ratio of the number of turns between the two coils determines the amount of voltage increase or decrease.

How A Transformer Increase Voltage？

A transformer increases voltage by using two coils of wire, a primary coil and a secondary coil, wrapped around a magnetic core. When an alternating current (AC) flows through the primary coil, it creates a changing magnetic field in the core, which in turn induces a voltage in the secondary coil. The voltage in the secondary coil is proportional to the turns ratio of the primary to secondary coil. For example, if the primary coil has 100 turns and the secondary coil has 500 turns, the voltage in the secondary coil will be five times higher than the voltage in the primary coil. This is called step-up transformer, which is used to increase voltage in electrical power transmission and distribution system.
