Share:
- 1Because there is a direct electrical connection and no electrical isolation between primary and secondary windings✓
- 2Due to the exceptionally high leakage impedance of the windings
- 3Because the output voltage variations are non-continuous and discrete
- 4Due to excessive copper losses at high voltage conditions
Correct answer
Because there is a direct electrical connection and no electrical isolation between primary and secondary windings
