The heat generated in the transformer is dissipated primarily by which process

Electrical Engineering XYZ MCQs

The heat generated in the transformer is dissipated primarily by which process:

1. Convection
2. Radiation
3. Conduction
4. All of these

Correct answer: 1. Convection

Explanation: The heat generated in the transformer is dissipated primarily by which convection process. This is the process where heat is transferred through the movement of fluids (liquid or gas). In a transformer, oil is often used as a cooling medium. Heat generated within the transformer is transferred to the oil, and convection currents carry the heated oil to the surface where it can dissipate the heat into the surrounding environment.
