electrical energy
You use an electric motor.
Electrical energy, converted to mechanical energy by an electric motor.
You use electrical energy.
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
The electrical energy is converted to heat.
they use electrical and sound energy
An electric clock typically uses electrical energy, which is converted into mechanical energy to power the movement of the clock hands. The electrical energy is provided by a power source such as a battery or a wall outlet.
An electric dynamo converts mechanical energy into electrical energy by way of moving electrical conductors in a magnetic field. Bicyclers use them to power their headlights and taillights.
Electric energy can be converted into heat through resistive elements like heating coils or electric stoves. It can be converted into motion through electric motors, which use electromagnetic forces to generate rotational or linear motion.
A PS3 must be plugged in to an electric outlet
