Multimeter: principles of measurement of dc voltage?
Hello Laxmi,
There are basically two types of multimeter:-
- Analog Multimeter
- Digital Multimeter
Analog Multimeter:-
Analog meters are a multifunctional multimeter that operates based on electrical mechanical movement. Analog meters use a printed linear or nonlinear background and a mechanical pointer. The pointer moves as a result of the flow of current through a built-in coil, the presence of electrical pressure, or the internal power source that is needed for resistance measurements.
Digital Multimeter:-
A digital multimeter (DMM) is a multifunctional meter that displays its electrical quantitative values on an LCD screen. A digital multimeter much like an analog meter, it is able to read voltage, current, and resistance. What makes a digital multimeter differ from the analog meter is its ability to display measured electrical values quickly without any computations.
Hope this helps.
