Sähköjännitemittarit
Sähköjännitemittarit, known in English as voltmeters, are instruments used to measure the electric potential difference between two points in an electric circuit. This potential difference is commonly referred to as voltage. Voltmeters are essential tools for electricians, engineers, and hobbyists alike, providing critical information about the operational status and health of electrical systems.
There are several types of voltmeters, broadly categorized by their operating principles. Analog voltmeters typically use
When connecting a voltmeter to a circuit, it is crucial to do so in parallel with the
