In measuring a voltage, a voltmeter uses some current from the circuit. Consequently, the voltage measured is only an approximation to the voltage present when the voltmeter is not connected. Consider a circuit consisting of two 1760- resistors connected in series across a 50.0-V battery. (a) Find the voltage across one of the resistors. (b) A voltmeter has a full-scale voltage of 50.0 V and uses a galvanometer with a full-scale deflection of 6.85 mA. Determine the voltage that this voltmeter registers when it is connected across the resistor used in part (a). Voltmeter Rv WW
