Q.6 What is the purpose of transformer?
Answer
A transformer is a static electromagnetic device engineered to rigorously step up or step down alternating voltage levels while strictly maintaining absolutely constant frequency.
A transformer is an absolutely essential static electrical machine that systematically transfers alternating electrical energy from one circuit strictly to another through shared magnetic coupling, without any physical electrical contact or moving mechanical parts.
It rigorously operates on Faraday's fundamental law of mutual electromagnetic induction. Its primary utility is to explicitly step up (increase) or step down (decrease) the magnitude of alternating voltages while keeping the supply frequency completely constant.
By stepping up the transmission voltage, the associated current is mathematically reduced proportionately, which strictly minimizes the ohmic power losses during long-distance energy transmission.
