Question

What are the basic characteristics of a transformer?

Answer 1

Transformer: -

1. A device that steps up or steps down the voltage as it transmits electrical energy from one alternating-current circuit to one or more other circuits.
2. Transformers are used for a wide range of functions, including raising the voltage from electric generators to enable long-distance transmission of electricity and lowering the voltage of conventional power circuits to run low-voltage devices like doorbells and toy electric trains.

Characteristics of a transformer: -

Constant Period
A transformer operates at a steady frequency. Both the input voltage and the output voltage have the same frequency.

Varying Voltage
A transformer's input and output voltages are adjustable. The supply voltage can be raised or lowered via a transformer.

Changing Current

In a transformer, the current is another variable parameter that can be raised or lowered.

Continuous Power

1. The transformer's output power remains constant.
2. The power delivered by the transformer and the power that is supplied to it are both the same.
