DMM stands for Digital Multimeter. It's a versatile electronic test instrument that combines the functionalities of several meters into one compact unit. DMMs are essential tools for anyone who works with electronics, allowing them to measure various electrical properties of circuits and components.
Here's a breakdown of what a DMM can typically measure:
Voltage (V): This is the potential difference between two points in a circuit. DMMs can measure both AC (Alternating Current) and DC (Direct Current) voltage.
Current (A): This is the flow of electrons in a circuit. DMMs can measure both AC and DC current.
Resistance (?): This is the opposition to current flow in a conductor.
