1. Find the resistance of the light bulb in this circuit. The cell is 1.5 V, and the ammeter is reading 85
mA (1000mA = 1 A).
2. Draw a circuit that has two light bulbs connected in series with a 9 V battery and an ammeter.
a. If the same light bulbs as in the last problem are used, what is the current on the ammeter?
(Hint: because there are two light bulbs there is twice as much resistance as above)
3. The school’s fire alarm consists of a circuit that has a 150 Ω buzzer, and a 100 Ω blinking light
connected in series with a 110 V power source, and a switch (closed when someone pulls the fire
alarm).
a. Draw this circuit.
b. Find the current that flows through this circuit when someone pulls the alarm.
4. Draw a circuit with a 10 kΩ resistor, a cell, an ammeter, and a switch all in series.
a. If the ammeter reads 155 mA what is the potential difference across the cell.
5. Indicate whether you would connect cells in series or parallel to do the following.
a. increase current
b. increase voltage

6. For the following circuits, indicate whether the bulb(s) will be normal brightness, ½ brightness, or
2x brightness. (One cell, connected to one bulb is NORMAL brightness)
a. One cell, two bulbs in series.
b. One cell, two bulbs in parallel.
c. Two batteries in series, two bulbs in series.
d. Two batteries in parallel, two bulbs in parallel.
7. This circuit has three batteries and four bulbs. Predict which bulbs are lit in this circuit under the

8. The chemical reaction used to make electricity in a cell can only make about 1.5 volts; yet the
modern car runs on 12 V. How do cars get enough energy from this reaction?
