5) What is the advantage of using digital multimeter?

Accuracy Linear scale Easy portability Logarithmic scale

Correct Answer: Accuracy

Explanation:

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.
Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance.
