Electronics Worksheet: Parallel Circuits

Electronics lesson 9: Parallel circuits · Set 327 · 40 questions

Remember (A path for each): Each bulb has its own path: removing one leaves the others glowing. Each bulb gets the full battery voltage. Total current = add the current of each path (n identical bulbs → n × one bulb’s current).
