➂
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
➃
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
➄
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.
