What is transformer and its function?

A transformer is an electrical device designed and manufactured to step voltage up or step down. Electrical transformers operate on the principle of magnetic induction and have no moving parts.

What is the basic function of a transformer in Mcq?

The basic functionality of a transformer is to transfer electrical energy from one circuit to another.

What is the function of transformer in power supply circuit?

Transformer: The transformer changes the incoming voltage to the needed outgoing voltage level. These devices may step up or step down the voltage. Typically, the DC voltage required is much less than the incoming AC voltage from the primary power source.

What is the function of conservator in transformer?

The function of a conservator is to take up contraction and expansion of oil without allowing it to come in contact with outside air.

How many types of transformers are there in physics?

There are basically two main types of transformers step-up transformer which converts a low input voltage into high output voltage and step-down transformer which converts high input voltage to low voltage. Transformers are used for regulating AC current, rectification, battery charging, etc.

What is the function of step up transformer?

Step-up transformer. The step-up transformer is a type of transformer with the function of converting low voltage (LV) and high current from the transformer’s primary side to high voltage (HV) and low current value on the transformers’ secondary side.

What is the function of the power 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 a transformer type power supply?

Transformer. Transformers convert AC electricity from one voltage to another with little loss of power. Transformers work only with AC and this is one of the reasons why mains electricity is AC. Step-up transformers increase voltage, step-down transformers reduce voltage.
