easuring a voltage, a vol lently, the voltage measured is only to the voltage present when the voltmeter is not connected. Consider a circuit consisting of two 1830- resistors connected in series across a 70.0-V battery. (a) Find the voltage across one of the resistors. (b) A voltmeter has a full-scale voltage of 70.0 V and uses a galvanometer with a full-scale deflection of 4.34 mA. Determine the voltage that this voltmeter registers when it is connected across the resistor used in part (a). R Voltmeter Ry www V R
