The electric motor converts electrical energy to:?

Question

A. radiant energy
B. mechanical energy
C. chemical energy
D. nuclear energy
E. thermal energy

Answer 1

mechanical energy, B.

Answer 2

Primarily the Electric Motor converts electrical energy to Mechanical energy - the motor turns.

But the motor also produces heat - thermal energy - from the resistance to electrical flow in the wires.

And this heat radiates out so electricity also produces thermal radiant energy.

Answer 3

Electric motors convert electrical into mechanical energy with a certain efficiency. For exampe (cf link below), a 4 kW, 4-pole Eff1 class motor has a minumum efficiency of 88.3% (at full load), i.e. at least 88.3% of electrical energy input will be converted to mechanical energy. The remaining 11.7% will be converted to heat through losses in stator & rotor, friction, ...

In practice, motors operate at a wide variety of loads. Voltage unbalance and harmonics can have significant impact on motor efficiency.

Answer 4

"Motors convert electrical energy to mechanical energy. Generators, the reverse, convert electrical enegy to mechanical energy." You mean, "Generators, the reverse, convert mechanical energy to electrical energy." This is simply because most physical processes are (theoretically) reversible.

Answer 5

B) mechanical energy

Answer 6

B.

But it also converts a small amount to E.
B is the best answer. If a choice for both B and E was there, that would be the real best answer.
