What is the purpose of a transformer in a circuit?

What is the main purpose of transformer?

A transformer is an electrical device that trades voltage for current in a circuit, while not affecting the total electrical power. This means it takes high-voltage electricity with a small current and changes it into low-voltage electricity with a large current, or vice versa.

What is the purpose of a transformer and how does it work?

A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle.

What happens when a transformer blows?

When a transformer blows, it interrupts electrical service to any residences or businesses connected to the transformer. Electric service crews must replace the destroyed hardware, first shutting down the incoming electrical line to prevent damage and injury.

What would happen if a transformer is connected to a DC supply?

If the primary of a transformer is connected to the DC supply, the flux produced in the primary will be of constant magnitude because of DC current. … So the transformer can be damaged due to this high current, if it is connected to DC supply.

What is the purpose of the transformer in DC power supply?

The transformer’s main function is to step-down (lower the amplitude) or step-up (increase the amplitude) the signal to produce the desired DC level required at the output of the power supply. The transformer also plays the role of an isolator.
