In a transformer the energy is conveyed from primary to secondary_________?
Correct answer: C. by the flux
- A. through cooling coil
- B. through air
- C. by the flux
- D. none of the above
Explanation
The alternating primary current produces magnetic flux in the core, and changing mutual flux induces the secondary voltage, transferring energy between windings. Cooling coils only remove heat and do not convey transformer energy.
