Repeat Problem 49 if the 500-kΩ resistor of Figure 6-89 is replaced with a 2-MΩ resistor.
Problem 49
A voltmeter having a 1-MΩ internal resistance is used to measure the indicated voltage in the circuit shown in Figure 6-89.
a. Determine the voltage reading which will be indicated by the meter.
b. Calculate the voltmeter's loading effect when used to measure the indicated voltage.
The can's initial volume at 5 °C is 7.2 × 10-4 m3. The coefficient of volume expansion for aluminum is 69 × 10-6 (C°)-1. When the can and the liquid are heated to 87 °C, 7.0 × 10-6 m3 of liquid spills over.
