Build circuits from descriptions

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

Build circuits from descriptionsBuild a series circuit with a power supply, two lamps and one switch. After you have built it, draw the circuit diagramBuild 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

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.
