Explain how the use of transformers is helpful in preventing the transmission losses?
In an electrical appliances to adjust the alternating voltage power transformers are used. Transformers are used to transform power from one circuit to another with the same frequency operates on AC power which works on mutual induction principle. To generate electrical power at very low voltage level which is very cost effective which results in greater line current also causes more line losses. If the voltage is increased, then the current reduced, which causes losses in the system also improves voltage regulation.
