Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 274 · 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 OFF and D is ON. Does the bulb glow? (a) No (b) Yes
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 OFF, B is OFF and C is OFF. Does the bulb glow? (a) No (b) Yes
3. 3.🔘 Which kind of switch closes when tipped over? (a) a toggle switch (b) a reed switch (c) a tilt switch (d) a slide switch
