A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a galvanometer and series resistor. Meters using WebFor the test circuit shown in Figure 5.24, derive an expression for the output voltage, Eo, as a function of the input voltage, Ei, and the resistances shown for (a) the ideal case of the perfect voltmeter having Rm = 0o and (b) the non-ideal voltmeter case when Rm is finite.
