Unformatted text preview: Parallel
Keeping the 12 volt dc source, add a second resistor (of diﬀerent value) to the circuit so that
you have two resistors in series. Calculate the new resistance, given by R = R1 + R2 , and
check by measuring with the DMM. Measure the new current in the circuit. Also measure
the voltage across the series combination of resistors and the voltage across each resistor.
Reconﬁgure the circuit so that the resistors are now in parallel. The new resistance is
calculated from R = R1 R2 /(R1 + R2 ). As before, measure the total resistance, the voltage
across the parallel combination, the current in the circuit and the current in each resistor. Results and Discussion
Tabulate your results carefully, and discuss as fully as possible the relationship between the
source voltage, resistance, the voltage across each resistor and the current(s) in the circuit
for both the series and parallel conﬁgurations. 11...
