1. Construct a circuit that has two light bulbs in series connected to a battery. Include a meter in the circuit that will be used to measure the current.

3. A R1 R2 2. How did you construct the circuit?
a. Now set the meter dial.
b. Finally complete the circuit. A R1 R2 3 3 3

4. 3. Measure and record the current.
I = ____________ A R1 R2 4 4 4

5. 4. Measure and record the voltage across the battery and both of the bulbs.VB V2
VB = _______
V1 = _______
V2 = _______ 5 5 5

6. 4. How does VB compare to V1 and V2?
5. What conclusion can you come to? 6
