Devices such as magnetic solenoids and loudspeakers that convert electricity into motion but do not generate usable mechanical power are respectively referred to as actuators and transducers.

Because they convert electricity into laser light with much higher efficiency, diode lasers also run cooler, which in turn allows them to be operated at much higher frequencies.

A crankcase heater generally has the same electrical symbol as a resistor because it converts electricity directly into heat via electrical resistance.

When converting electricity into mechanical power, brushless motors are more efficient than brushed motors.
