Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice. The voltmeter in Figure P19.76 has an internal resistance of and is used to measure the voltage across a resistor with as shown. How much does this non ideal voltmeter affect the circuit? That is, attaching the voltmeter changes the voltage across What is the fractional change in the voltage across when the voltmeter is attached?
