- 4. 04 What is the use of Multimeter? A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings Atheena Pandian
- 5. A basic multimeter measures resistance, voltage and current. More advanced models can measure capacitance, inductance, and temperature They may also be able to measure frequency and duty cycle (a measurement relating to pulse systems such as fiber optic networks). 1. 2. 3. 05 Three Different Functions
