Applications:

Digital multimeters (DMMs) are the primary tool for electrical troubleshooting, used to measure voltage, current, and resistance across a wide range of electronic and electrical circuits. They are essential for tasks like diagnosing car battery health, checking household wiring, and verifying component values in electronics repair.


Measuring Principle:

Digital multimeters (DMMs) work by converting the electrical quantity (voltage, current, or resistance) being measured into a proportional analog voltage, which is then processed by an Analog-to-Digital Converter (ADC) to display a precise numerical reading. They use shunt resistors to measure current and voltage dividers to measure high voltage, all routed through this core ADC principle.
