Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 554 · 40 questions

Remember (All for series, any for parallel): Series switches (one path): the bulb glows only if ALL are ON. Parallel switches (side-by-side paths): the bulb glows if ANY one is ON. Mixed: work out each path, then ask if there is at least one complete path.

2. 2.🔘 Two switches are in parallel (side by side). When does the bulb glow? (a) only when both are OFF (b) never (c) only when both are ON (d) when either is ON
3. 3.What does a toggle switch do? (a) slides side to side (b) works only while pressed (c) springs back when let go (d) flips up or down
