SUMMARY
In older houses, the dimming of lights when a refrigerator starts is due to the high initial electrical load required to start the motor, which contrasts with the steady current drawn by an electric heater. This phenomenon highlights the difference between the transient load of a motor during startup and the constant load of a resistive heater. Additionally, a motor can act as both a motor and a generator simultaneously; it converts electrical energy into kinetic energy and can also convert kinetic energy back into electrical energy through induction. Generators, on the other hand, produce electrical forces that oppose the applied kinetic forces, affecting their efficiency and operation.
