6.2015503875969 V.]
QUESTION:
If the internal resistance of the meter were 14 M ΩΩ, what is the
voltage across R2R2?
Thanks ahead
Homework Answers
with the meter disconnected the voltage across R2 is calculated using voltage division rule.
with the meter connected, the effective resistance of R2 parallel with Ri is calculated and the voltage across R2 is calculated.
with Ri=14Mohm the effective resistance is calculated and the voltage across R2 is calculated.

Although an ideal voltmeter has an infinite
internal resistance, this theoretical ideal is usually not met in
practice. The voltmeter in the Figure has an internal resistance of
7 x 109 Ω and is used to measure the voltage across the
resistor R2 as shown. Attaching this non-ideal voltmeter
decreases the voltage across R2. Calculate the magnitude
of this decrease using an emf of 16 V and R1 =
R2 = 200 kΩ.
