GENERATOR

Generator or referred also as a dynamo, is an appliance that change mechanic energy to electric energy. The work principle of generator is based on electro magnetic induction principality. If a wire is moved so that it cuts a magnetic field (the lines of force), hence at wire will be generated an electro motive force. Electro motive force will cause incidence of electric current that flows through the wire and generated electro motive force depend on magnetic field strength and wire speed to cut the lines of force. Increasing the density of the field or increasing the speed of the wire therefore increases the voltage.
