Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 719 · 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) No (b) Yes
2. 2.🔘 Which kind of switch slides side to side? (a) a tilt switch (b) a toggle switch (c) a slide switch (d) a reed switch
3. 3.What does a push button do? (a) closes when tipped over (b) stays where you flip it (c) closes near a magnet (d) works only while pressed
