When I place the voltmeter probes across the battery terminals to measure the potential difference of the battery, does the internal resistance of the voltmeter have to be low or high? Think of this act as the circuit below. (We don't want the influence of the voltmeter to change our circuit paths by including it to measure voltage so...) Voltmeter R component to be measured a. The inter resistance of the voltmeter must be low to allow large current through to read the voltage (connected in parallel effectively) O b. The internal resistance must be high so current is not significantly effected by the presence of the voltmeter (connected in parallel effectively) O c. The voltmeter is connected in series when measuring voltages d. The voltmeter cant measure potential difference

Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice. The voltmeter in the Figure has an internal resistance of 6 x 10 2 and is used to measure the voltage across the resistor R, as shown.
