An auto-transformer having a transformation ratio of 0.8 supplies a load of 10 kW. The power transferred inductively from the primary to the secondary is _______ kW .
-
- 1 kW
- 2 kW
- 3 kW
- 4 kW
Correct Option: B
If transformation ratio were unity, whole power would have been transferred conductively only. Power transferred inductively
| = Total poewr × |  | 1 - |  | = 10 × (1 - 0.8) = 2 kW | |
