Series And Parallel Circuits Worksheet Grade 8 -

In Grade 8 science, understanding circuits involves identifying the components and comparing how current and voltage behave in different setups

• Answer: The first bulb might have a lower resistance, or they are not identical. In a true series circuit with identical bulbs, they are equally bright. If one is dim, check the wire connections for corrosion.

Part C: Circuit Analysis

16. 9V ÷ 3 = 3V per bulb
17. Each bulb gets 9V because each branch connects directly across the battery.
18. All bulbs go out because the single path is broken.
19. The other bulbs stay lit because current still flows through other branches.
20. Circuit B (parallel) – each bulb gets full battery voltage; in series, voltage is shared.
21. Circuit B – lower total resistance draws more current from the battery.
