How is potential difference measured
Web2 feb. 2024 · A voltmeter can be used to measure the difference in electrical potential between the two compartments. Opening the switch that connects the wires to the anode and the cathode prevents a current from flowing, so no chemical reaction occurs. WebThe potential at a given point can be found by first finding E and then carrying out this integral. These differences in potential energy are measured with a voltmeter. The potential difference between two points equals the amount of work that would be required to move a unit positive test charge between those points.
