jännitemittari
Jännitemittari, also known as a voltmeter, is an instrument used to measure the electric potential difference between two points in an electric circuit. This potential difference is commonly referred to as voltage. Jännitemittarit are essential tools for electricians, engineers, and hobbyists working with electrical systems. They help diagnose problems, verify circuit operation, and ensure safety.
There are several types of jännitemittarit. Analog jännitemittarit use a needle that moves across a calibrated
To use a jännitemittari, it is connected in parallel across the component or points where the voltage
