5 PrincipleThe principle of electromagnetic induction to generate electrical energy from mechanical energy Electromagnetic induction involves the generation of an electrical current in a conductor when the conductor is moved through a magnetic field.
6 How do we increase electricity Demonstration with alternator on how electricity is generated. How can we increase electricity
7 Increasing CurrentIncreasing the speed of the conductor through the magnetic field. Increasing the number of conductors passing through the magnetic field Increasing the strength of the magnetic field.
8 AC and DCAC– Alternating current DC– Direct Current Alternator generates AC voltage. Automotive battery and vehicle system using DC voltage.
9 AC and DCSo what changes the AC to DC voltage. The voltage Rectifier. Rectifiers are consisted with six diodes. Diodes are one way check valves that only allow current to flow one way.
