Transformers working principle and what is power factor

Question

Accepted Answer

Transformers are devices that transfer electrical energy between two or more circuits through electromagnetic induction. Power factor is a measure of how effectively electrical power is being used in a circuit.

Transformers work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a nearby coil of wire.
They are used to step up or step down voltage levels in electrical power transmission and distribution systems.
Power factor is the ratio of real power (measured in watts) to apparent power (measured in volt-amperes) in an AC circuit.
A power factor of 1 indicates that all the power supplied to the circuit is being used effectively, while a power factor less than 1 indicates inefficiency or reactive power.
Power factor correction techniques, such as adding capacitors to the circuit, can improve power factor and reduce energy wastage.

Accepted Answer

Transformer working depends on the mutual induction. Pf is defind as the ratio of real power flowing to the load, to the apparent power in the circuit
