  1. Electronics… And more practical uses of electricity

  2. Current types: • Alternatingcurrent (AC) • Direct current (DC)

  3. ElectricalFunctions • 1. Power supply: • Supplies energy to the circuit • Examples: Battery, power supply, photovoltaiccell • 2. Conduction: • Ability to transferelectrons

  4. Factorsthat affect conduction • Length: • The shorter the wire the better the conductor • Diameter • The wider the wire the better the conductor • Temperature • The colder the wire the better the conductor • Nature of the material • A metalisbetterthan a metalloid (carbon) whichisbetterthan a non-metal

  5. 3. Protection: • Elementwhose goal is to protect the circuit in case of a surcharge

  6. a) Fuse

  7. b) Breaker

  8. Electricalfunctionscontinued • 4. Insulation: • Elementwhosefunctionis to slow down the electricalcurrent

  9. a) Resistors

  10. p.468

  11. Printed circuits

  12. ElectricalFunctions • 5. Control • Component that has the ability to control the flow of electricity in a circuit • Flip flop switch, lever switch, push button, magnetic switch

  13. Defining switches • UniPolar vs. Bipolar • Unidirectional vs Bidirectional

  14. ElectricalFunctions • 6. Transformation of energy • Any component that has the ability to transformelectricalenergyintoanotherform of energy (heat, light, magnetism, vibration)

  15. 7. Relay • Function: Elementthat uses a smallamount of power to switch another circuit whichrequires a largeramount of power

  16. 8. Condenser (Capacitor) • Function: Stores energy • Allows to even out currentfluctuations • Allows to dischargestoredenergy in one shot (e.g. camera flash)

  17. 9. Diode • Allows the current to flow in only one direction • Has lowresistance one way, incredibly high resistance the other) • ConvertsAlernatingcurrentinto direct current

  18. 10. Transistor • Function: Amplifies an electronic signal • Used in computers – binary code
