Question

Why are transformers so important for the transmission of energy?

Answer 1

1. Transformer is a device by which the emf of an alternating current is increased or decreased according to the requirement.
2. By using the transformers we can either increase or decrease the voltage. This is necessary for the power transmission since the power loss due to current decreases if we step up the voltage.
3. In this way, transformers are important for the efficient transmission of energy.
