  1. B A Ohm’s Law Quiz – take up What are the coordinates for the two points? A(0,0) B(0.8,4) What is the difference in the y coordinates between A and B? RISE  4 – 0 = 4 V What is the difference in the x coordinates between A and B? RUN  0.8 – 0 = 0.8 A SLOPE = RISE = 4 RUN 0.8A SLOPE = 5 OHMS SNC1D | A. Manaktola

  2. Ohm’s Law Quiz – take up 2) An ammeter measures how many coulombs of charge passes through a point per second. 3) The above circuit is a series circuit, and the voltmeter and ammeter are all connected in series. 4) 1 Ohm = 1 Volt/Ampere TRUE FALSE TRUE SNC1D | A. Manaktola

  3. Series & Parallel Circuits SNC1D | A. Manaktola

  4. B A Today’s Circuit Which light bulb will be brighter: A or B? Why? SNC1D | A. Manaktola

  5. Video Clip SNC1D | A. Manaktola

  6. 6V B A 3V In series… In parallel… The higher the voltage drop across a bulb, the brighter the bulb will shine. Suppose the battery is 6V. What will be the voltage drop across each bulb? SNC1D | A. Manaktola

  7. 6V B A 3V Today’s Circuit Which light bulb will be brighter? B Bulbs connected in parallel do not “share” the voltage drop. The voltage drop across the battery is the same as the voltage drop across each of the loads in the circuit. As more bulbs are added in series, the voltage drop is “shared” among the loads. Therefore, the more bulbs you add, the dimmer each of the bulbs will be. Why? SNC1D | A. Manaktola

  8. Let’s Try it! SNC1D | A. Manaktola

  9. Summary V = Voltage drop, or Electrical Potential Difference ** Note: We are assuming the loads in the circuit are identical SNC1D | A. Manaktola

  10. Stay tuned… To find out what happens to RESISTANCE in series and parallel circuits SNC1D | A. Manaktola
