A multimeter is an electronic measuring instrument that can measure multiple electrical properties, including voltage (volts), current (amperes), and resistance (ohms). Some advanced models can also measure capacitance, frequency, temperature, and perform other functions.
Multimeters come in two main types:
- Analog Multimeters: Use a moving needle to display readings on a dial.
- Digital Multimeters (DMMs): Display readings on a digital screen, making them easier to read and often more precise.
They are essential tools for electricians, engineers, and hobbyists for diagnosing electrical issues, testing circuits, and ensuring proper functionality of devices.
