F2 Science Electricity Exercise Top
D1. Diagram must show correct symbols: two cells (+ – + –), switch, bulb, ammeter in series, voltmeter in parallel across bulb.
D2.
| Circuit | Type | Bulb brightness | If one bulb breaks, other? |
|---------|------|----------------|----------------------------|
| A | Series | Dimmer | Does not work |
| B | Parallel | Same brightness | Works | f2 science electricity exercise top
Practice and reinforce key F2 (Year 8) electricity concepts: circuits, components, series vs parallel, conductors/insulators, and safe handling. Circuit: A 9V battery connected to two parallel branches
Use the words from the box below.
| Current | Voltage | Resistance | Series | Parallel | Ammeter | Voltmeter | Conductor | Insulator | Ohm’s Law | ammeter in series
Circuit: A 9V battery connected to two parallel branches. Branch 1 has a single 3Ω resistor. Branch 2 has a single 6Ω resistor.
Q7. Calculate the current flowing through Branch 1. (( I = V/R )) Q8. Calculate the current flowing through Branch 2. Q9. Calculate the total current drawn from the battery. Q10. Top Question: If you add a third bulb in parallel to the first two, what happens to the brightness of the original two bulbs? Explain why.
