Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 467 · 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.

3. 3.What does a reed switch do? (a) closes when tipped over (b) flips up or down (c) slides side to side (d) closes near a magnet
4. 4.🔘 Which kind of switch works only while pressed? (a) a reed switch (b) a tilt switch (c) a slide switch (d) a push button
