Suppose that in Figure 3.3, Vo=13V, R1=250kphm, R2=375kohm, and Ri=1.9Mohm. Initially, the voltmeter is disconnected.

EXAMPLES:

What is the voltage across R2? [Answer: 7.8 V.]

What is the voltage across R2 with the meter connected? [Answer: 7.22926829268293 V.]

QUESTION:

If the internal resistance of the meter were 15 M , what is the voltage across R2?
