®
Now connect the parallel circuit below, using all three resistors. Measure the voltage across
each of the resistors and the combination, taking care with the polarity as before.
NOTE: Keep all three resistors connected throughout the time you are making your
measurements. Write down your values as indicated below.
Parallel
Now connect the circuit below and measure the voltages. You can use the resistance read-
ings you took in Experiment 4 for this step.
Combination
Use the three unequal resistors that you used in Experiment 4 to construct the circuits shown
below. Make the same voltage measurements that you were asked to make before in steps 1
to 4. Use the same resistors for A, B and C that you used in Experiment 4.
