- 1. Principle of Electrical Presenter: Noraide Md Yusop Rosazmir Mat Rashid Mohd Norhisham Nordin Azhar Md Saad Chin Seng Fatt
- 2. Contents 1 Electrical Circuit 2 Ohm’s Law 3 Series & Parallel Circuit 4 Measuring Current 5 Measuring Voltage 6 Conclusion
- 3. ELECTRICAL CIRCUITS All you need to be an inventor is a good imagination and a pile of junk. -Thomas Edison
- 4. Ohm’s Law I=V/R I V = Voltage (Volts) R Georg Simon Ohm (1787-1854) = Current (Amperes) (amps) = Resistance (ohms)
- 5. How you should be thinking about electric circuits: Voltage: a force that pushes the current through the circuit (in this picture it would be equivalent to gravity)
- 6. How you should be thinking about electric circuits: Resistance: friction that impedes flow of current through the circuit (rocks in the river)
- 7. How you should be thinking about electric circuits: Current: the actual “substance” that is flowing through the wires of the circuit (electrons!)
- 8. Would This Work?
- 9. Would This Work?
- 10. Would This Work?
- 11. The Central Concept: Closed Circuit
- 12. circuit diagram Scientists usually draw electric circuits using symbols; cell lamp switch wires
- 13. Ohm’s Law Simulation Click Here
- 14. Series and Parallel Circuits Series Circuits only one end of each component is connected e.g. Christmas tree lights Parallel Circuits both ends of a component are connected e.g. household lighting
- 15. series circuit • voltage is shared between the components 3V 1.5V 1.5V
- 16. parallel circuit • voltage is the same in all parts of the circuit. 3V 3V 3V
- 17. Simple Circuits Series circuit All in a row 1 path for electricity 1 light goes out and the circuit is broken Parallel circuit Many paths for electricity 1 light goes out and the others stay on
- 18. measuring current Electric current is measured in amps (A) using an ammeter connected in series in the circuit. A
- 19. measuring current This is how we draw an ammeter in a circuit. A A SERIES CIRCUIT PARALLEL CIRCUIT
- 20. measuring current SERIES CIRCUIT • current is the same at all points in the circuit. 2A 2A 2A PARALLEL CIRCUIT • current is shared between the components 2A 2A 1A 1A
- 21. measuring voltage The ‘electrical push’ which the cell gives to the current is called the voltage. It is measured in volts (V) on a voltmeter V
- 22. measuring voltage This is how we draw a voltmeter in a circuit. V SERIES CIRCUIT V PARALLEL CIRCUIT
- 23. measuring voltage Different cells produce different voltages. The bigger the voltage supplied by the cell, the bigger the current. Unlike an ammeter, a voltmeter is connected across the components Scientist usually use the term Potential Difference (pd) when they talk about voltage.
- 24. Conclusion Ohm law is V = I / R Electric circuit has two types of connection Series circuit Parallel circuit • Voltage is measured using voltmeter by connected across the components • Current is measured using ammeter by connected in series in the circuit.
