A 6-pole lap-connected dc generator with 480 conductors has armature resistance of 0.06 ohm. If the conductors are reconnected to form a wave winding, other things remaining unchanged, the value of the armature resistance will be _______ ohm .
-
- 18 ohm
- 54 ohm
- 0.54 ohm
- 5.4 ohm
Correct Option: C
| Rlap = | . | |||
| p2 | A |
| and Rwave = | . | |||
| 4 | A |
| = | = | = | = | ||||||
| Rwave | p2 | 62 | 36 | 9 |
∴ Rwave = Rlap × 9 = 0.06 × 9 = 0.54 Ω
