hook an electric motor to the axle
A generator changes mechanical energy into electrical energy.
A dam does not transform mechanical energy from the motion of water into electrical energy. A turbine can convert the kinetic energy of moving water, coming from a dam, a river, or anywhere, into mechanical energy, which a generator then takes to convert that into electrical energy.
It doesn't. It converts electrical energy to mechanical energy. Electricity drives the rotor which has inclined blades these move the air.
The generators transfer mechanical energy into very useful electrical energy.
You can transform thermal energy to electrical energy in a power plant, chemical energy to mechanical energy in an internal combustion engine, or nuclear energy into thermal energy in a nuclear reactor. These are just three examples.
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
electrical to mechanical
Mechanical energy
Batteries transform chemical energy to electrical energy. The electrical energy is released during a chemical reaction inside the battery.
A galvanometer is an instrument that is used to measure current or voltage. It can have a mechanical movement, ie a needle that moves round a scale, or it can be digital as many are now.
The motor changes electrical energy into mechanical (torque) energy.
It uses electrical energy,mechanical energy.
