In a transformer the energy is conveyed from primary to secondary through:
- Metal
- Air
- Flux
- none of the above
Correct answer: 3. Flux
Explanation: The transformer is an electrical device that changes ac electrical power from one voltage level to another through the action of the magnetic field.
A transformer comprises two or more coils of wire that are usually not directly connected. The connection between coils is a common magnetic flux.
In a transformer the energy is conveyed from primary to secondary through flux.
