  1. Starter – True or False???? • The battery forces charge to flow around the circuit. • The Charge in the circuit comes from the battery • Increasing the number of batteries in the circuit increases the current • The bulb filament lights up as the charged particles hit the particles in the filament, causing them to heat up and give off light. • Current does not flow • A bulb in a circuit uses up charge • A bulb in a circuit uses up energy • Charge is measured in Amps

  2. Investigating current in a series circuit . Draw circuit diagram . Record Ammeter Readings, A1, A2, A3 . Comment on the brightness of the bulbs and the Ammeter readings. A1 A3 A2 • Conclusions – • - The bulbs get dimmer when they are added in series. • -The current around a series circuit is the same at all points. • - The current in = current out

  3. Why? • Resistance! The extra bulb adds extra resistance to the circuit. • The flow of charge reduces. (current reduces)

  4. . Draw circuit diagram . Record Ammeter Readings, A1, A2, A3,A4 . Comment on the brightness of the bulbs and the Ammeter readings. A1 A4 A2 A3 • Conclusions – • The bulbs do not get dimmer. • The current through the bulbs in parallel is higher than if it were in series. • The current in = current out

  5. Why are the bulbs brighter in parallel?What are the effects on the battery?Advantages of a parallel circuit?

  6. Activity • Produce a circuit where one room has a maximum brightness light, and the other room has 2 dimmer lights. • Produce a circuit where all 3 rooms can have a light of maximum brightness. -Copy questions. -Draw circuit diagrams. -Construct the circuit.
