Voltmeters
A voltmeter is a device used to measure the electrical potential difference, or voltage, between two points in a circuit. Think of it as a tool that tells you how much electrical "push" is available to move electrons from one point to another. It’s connected across two points without significantly affecting the circuit's operation. Voltmeters are essential in troubleshooting electrical systems, ensuring components function correctly, and measuring energy differences in circuits. They are designed to be highly sensitive to voltage changes while drawing minimal current from the circuit.
