CIRCUIT DIAGRAMS
1. Two cell battery connected to three light bulbs in series.
2. One battery connected to two light bulbs in parallel. One light bulb is controlled by a
switch.
3. Two one-celled batteries in parallel, connected to three light bulbs in series. The bulbs are controlled by a
switch.
4. Three celled battery connected to two light bulbs in parallel and a third light bulb connected in series.
5. A one celled battery, a switch that controls the entire circuit, a motor and a light bulb. The motor must
continue to work, if the light bulb burns out.
6. Four bulbs are connected in series to a three celled battery with a switch and a properly placed fuse.

7. Two bulbs in parallel and a third in series are connected to a two cell battery and a switch that works on the
second bulb only.
8. Draw a series connection of a cell, a switch, and a bulb. Show the voltmeter connected to measure the
electrical potential of the source and an ammeter connected to measure the electric current in the circuit.
9. Three 3V cells connected in series, a switch, an ammeter for measuring the total current coming from the
cell, three light bulbs connected in parallel and a voltmeter for measuring the potential difference across the
second light bulb. The switch should control all three light bulbs at once. Label all positive and negative
terminals.
10. Four bulbs in all, two in parallel to each other placed between two in series, all connected to a three cell
battery. A switch, a fuse, an ammeter before the first light bulb and a voltmeter across the source.
