Electronics Worksheet: Switches in a Circuit

Electronics lesson 5: Switches in a circuit · Set 269 · 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.
