Designing and Drawing Circuits
1. Draw a circuit with 2 cells in series and 2 lightbulbs in parallel, each controlled individually by a
closed switch. Add a voltmeter to measure the potential difference of the source. Label the
positive and negative terminals of the source and the voltmeter. Indicate the direction of current
flow.
2. Draw a circuit with 2 cells in parallel, 2 resistors in series, and a switch to control the whole
circuit. Add a fuse to protect the circuit. Add an ammeter between the resistors. Label the
positive and negative terminals of the ammeter and the sources. Indicate the direction of current
flow.
3. Draw a circuit with 2 cells in series and 2 lightbulbs in series. Add a switch for the whole
circuit. Add an ammeter to measure the total current and a voltmeter to measure the potential
difference across one bulb. Label the positive and negative terminals of the ammeter and
voltmeter.
4. Draw a circuit with 3 cells in series and 3 lightbulbs, 2 of which are in series. Add a voltmeter
to measure the potential difference across the 2 series bulbs. Add a switch to control the branch
with only one bulb and add an ammeter to measure its current. Indicate the positive and
negative terminals of the ammeter and voltmeter. Indicate the direction of current flow.

5. Draw an electrical circuit involving four lightbulbs and a three-cell energy source set up in
parallel. Two of the bulbs are in series to each other and the other two are set up in parallel.
Attach three voltmeters in the appropriate fashion to measure the potential difference of the
battery, one of the series lamps, and one of the parallel lamps. Attach a fuse for the entire
circuit’s protection. Include four switches; one switch to control the entire circuit, one switch to
control the series lamps only, and one switch each for the parallel lamps so that they can be
individually controlled. One of the switches to the parallel lamps is open. All other switches are
to be closed. Attach four ammeters; one to measure the current of the entire circuit, one to
measure the current to the series lamps and one ammeter each to the parallel lamp circuits.
Indicate the direction that the current is flowing in the circuit.
6. Draw an electrical circuit involving 2 lightbulbs, a motor, 2 resistors, and two cells. The cells
are in parallel. The bulbs are in series to each other while the resistors and motor are in parallel.
Attach three voltmeters to take readings for the entire source, the second bulb, and the motor.
Position a fuse for the entire circuit’s protection. Include four switches; one to control the entire
circuit, one to control only the lamps, one to control the motor, and the fourth to control both
resistors together. All the switches are closed except the one controlling the motor. Attach five
ammeters; one to take the current of the entire circuit, one for the series lamps, one for the
parallel resistors together, one for the motor, and one for the first resistor only. Indicate the
direction of current flow.
