Electronics Worksheet: Series Circuits

Electronics lesson 8: Series circuits · Set 196 · 40 questions

Remember (One path for all): One path: if any bulb is removed or broken, no bulb glows. Identical bulbs share the voltage: each gets battery volts ÷ number of bulbs. More bulbs in series → each gets less → all glow dimmer.
