Question

Look at the circuit shown in the figure above. Switch S1 is open as shown, and R1 and R2 each have a value of 100 k. If you connect your meter's test probes to points A and B in the circuit, what voltage would you measure? A. 6 V B. 3 V C. 0 V D. 9 V

Answer 1

The batteries are connected in series so the voltage simply adds: 6v.

You must have a non-energized circuit to measure resistance with a meter so between c and d, switch open.
