Electrical Engineering And other practical uses of electricity Part 2

Basic Electrical Functions 6. Transformation of energy Any component that has the ability to transform electrical energy into another form of energy E.g. Electricity to heat (heating element) Electricity to light (light bulbs) Electricity to magnetism (solenoids) Electricity to kinetic (motor)

Transformation of energy A device can have many possibilities of transfomation of energy – CELL PHONES Display transforms electricity into light Sound transfomrs electricity into vibrations (sound waves)

Basic Electrical Functions 7. Relay Element that uses a small amount of power to switch another circuit which requires a larger amount of power

Basic Electrical Functions 8. Condenser (Capacitor) Component that stores energy Allows to even out current fluctuations Allows to discharge stored energy in one shot (e.g. camera flash)

Basic Electrical Functions 9. Diode Component that Allows the current to flow in only one direction Has low resistance one way, incredibly high resistance the other) Converts Alernating current into direct current

Basic Electrical Functions 10. Transistor Component that amplifies an electronic signal – Used in computers – binary code
