Physics · Electrical Machines
The correct induced electromotive force (EMF) equation for a DC generator is given by (where φ = flux/pole, N = speed in rpm, Z = total number of armature conductors, P = number of poles, and A = number of parallel paths):
- 1E = φNZ60PA
- 2E = φNZP60A✓
- 3E = φNZA60
- 4E = φNZA60P
Correct answer
E = φNZP60A
