1. The 10M resistor (all resistor values are in Ohms and M = million) represents a scope
input resistance. Calculate the voltage across the 2M resistor and compare (% error) to
the ideal case. An ideal scope input resistance is the same as an ideal internal
resistance of a voltmeter.

Replace the 2M resistor with a 100K resistor and calculate the voltage across the 100K
resistor and compare (% error) to the ideal case.
For which resistor value (2M or 100K) does the scope have the greatest “loading”
effect? Justify your answer.
1. When we build our level meter, we will need some fixed voltages to serve as
references for comparison. We can produce these voltage references
through the use of voltage division -- dividing down the positive voltage rail
used to power the op-amps. See Figure 4. Use your results from prelab to
choose values for R1, R2, and R3 such that V₁ = 8 V and V₂ = 4 V.
