WebHowever, what it says for voltmeters is not intuitive for me: ... A voltmeter should have a much larger resistance compared to any circuit element across which it is connected because a low internal resistance voltmeter would draw a current from the circuit which changes the very voltage across the circuit element you are trying to determine. WebLesson Explainer: Voltmeters. In this explainer, we will learn how to use voltmeters in electric circuits to measure the potential difference across a component in the circuit. Recall that when there is a potential difference between two points, this difference will exert a force on charges, resulting in a flow of charge between the points. d and d shirts
