Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 922 · 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.🔘 Switch A is on the main wire next to the cell and the bulb; then the wire splits into two side-by-side paths, one with switch B and one with switch C. A is ON, B is OFF and C is OFF. Does the bulb glow? (a) No (b) Yes
3. 3.🔘 What does a switch do in a circuit? (a) opens or closes the loop (b) changes the voltage (c) stores current (d) makes electricity
