1. Using batteries and bulbs (as resistors) set up the following circuit:
2. Properly place an ammeter into the circuit and measure the current
in amps (A):
Current =
3. Draw the circuit using symbols to show how you connected the
ammeter:
Disconnect the ammeter and re-set up the circuit.
4. Measure the voltage across each bulb:
V1 = V V2 = V
5. Using the equation V
R
I
calculate the resistance of each bulb.
6. What is the total resistance of the two bulbs together?
Rtotal =
7. Using your measured values for current (I) and total resistance (R)
confirm Ohm’s Law: V=IR and predict what the total voltage is.
VT =
8. Measure the actual total voltage across the all the batteries?
Voltage =
The measure voltage will likely be different because your measured
values of current and resistance contain error.
