How does a generator work?
- It uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit. This flows of electric charges constitutes the output electric current supplied by the generator.
- Modern-day Generators: Electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field. This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, which generating electric current.

How electricity is generated from Wind?
Wind turbines use the wind's kinetic energy to generate electrical energy, which then are able to be used at home, buildings, or businesses. Wind blows on the angled blades of the rotor,causing it to spin, converting some of the wind's kinetic energy into mechanical energy.

Process
- Generator- Shift and gearbox connects the rotor to a generator, so then the rotor spins as well as the generator also spins. After this the generator uses an electromagnetic field to convert this mechanical energy into electrical energy.
- Substation-The electric energy from the generator is converted along cables to the substation.
- Electricity transmission-The national grid uses high voltages to convert electricity through the power lines to the houses, buildings, and businesses that need the energy.
- Consumer homes and businesses-Other transformer reduce the voltage back down to a usable level for consumer or businesses to use.
