Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 109 · 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.

1. 1.🔘 A cell and a bulb are joined to 4 side-by-side paths with one switch on each path — A, B, C and D (parallel). A is OFF, B is OFF, C is ON and D is ON. Does the bulb glow? (a) Yes (b) No
2. 2.🔘 A cell and a bulb are joined to two side-by-side paths: path 1 has switches A and B one after another, path 2 has switch C. A is ON, B is ON and C is OFF. Does the bulb glow? (a) No (b) Yes
3. 3.🔘 Two switches are in series. When does the bulb glow? (a) when either is ON (b) when both are ON (c) never (d) when both are OFF
4. 4.🔘 A cell, a bulb and switches A, B and C are joined one after another in a single loop (series). A is ON, B is OFF and C is ON. Does the bulb glow? (a) No (b) Yes
5. 5.What does a tilt switch do? (a) closes when tipped over (b) slides side to side (c) closes near a magnet (d) flips up or down
6. 6.🔘 A bulb and a cell are joined through 2 switches on 2 side-by-side paths, one switch on each path (parallel). What is the smallest number of switches that must be ON to light the bulb?
