alleryIn a d.c. motor the energy transformation is
AChemical to electrical energy
BMechanical to electrical energy
CElectrical to mechanical energy
DHeat to mechanical energy
Answer & Solution
Correct answer: C. Electrical to mechanical energy
1. A motor receives electrical input and produces motion.
2. The current in the coil experiences a force in the magnetic field.
3. The torque rotates the shaft, doing mechanical work.
4. So electrical to mechanical.
