10. Build circuits from descriptions

11. Build a series circuit with a power supply, two lamps and one switch. After you have built it, draw the circuit diagram

12. Build circuits from descriptions Build a series circuit with a power supply, two lamps and one switch. After you have built it, draw the circuit diagram Build a parallel circuit with a power supply, one lamp and one switch in one of the two branches. In the other branch put two lamps. After you have built it, draw the circuit diagram

13. Compare an contrast the two circuits. You should include: A description of the type of circuits and the brightnesses of each lamp An explanation of the path of electrons around the circuit and the part played by the power supply in the circuit Links between the power calculations you made earlier and the brightnesses of the lamps A discussion of the power outputs for each of the two circuits.
