WebJun 11, 2024 · As you know, when secondary of transformer is connected to a load, current starts to flow. This current produce its own flux (let's say F2) which opposes the main flux (F1). Then E1 (back-EMF primary side) decreases and extra current starts to flow in primary side and this current cancels F2 flux out and the F1 kept constant in transformer. WebTransformer Basics. A transformer is a device that transfers electrical energy from one circuit to another by electromagnetic induction. The electrical energy is always transferred without a change in frequency, but may involve changes in amplitudes of voltage and current. Because a transformer works on the principle of electromagnetic ...
