9. An ideal Opamp has infinite input impedance but non-zero output impedance. The Opamp is used as a voltage follower interface for connecting a biomeasurement device to a voltmeter. If the voltmeter has an input impedance of 100Ω, what must the Opamp output impedance be to give a measurement error of less than 1%?

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.
