Consider the scale of a voltmeter

WebIn 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 1620-O resistors connected in series across a 61.8-V battery. (a) Find the voltage across one of the resistors.V (b ...
