Deep Dive: G4B06
The correct answer is C: Higher precision. An advantage of a digital multimeter as compared to an analog multimeter is higher precision. Digital meters can display more digits and have better precision than analog meters. For amateur radio operators, this provides more accurate measurements. Understanding this helps when selecting test equipment.
Why Other Answers Are Wrong
Option A: Incorrect. Digital meters aren't necessarily better for measuring computer circuits - both can measure DC voltages. Computer circuit measurement isn't a specific advantage. Option B: Incorrect. Digital meters aren't less prone to overload - both can be damaged by excessive voltage/current. Overload protection depends on design, not meter type. Option D: Incorrect. Digital meters aren't necessarily faster - response time depends on design. Speed isn't a consistent advantage.
Exam Tip
Digital multimeter advantage = higher precision. Think 'D'igital 'M'ultimeter = 'D'isplays 'M'ore digits (higher precision). Digital meters can display more digits and have better precision than analog meters. Not computer circuits, not overload, not speed - just precision.
Memory Aid
Digital multimeter advantage = higher precision. Think 'D'igital 'M'ultimeter = 'D'isplays 'M'ore digits. Digital meters can display more digits and have better precision than analog meters. Key advantage for accurate measurements.
Real-World Example
You measure a voltage. A digital multimeter displays 12.345 volts (high precision), while an analog meter might show 12.3 volts (lower precision). Digital meters can show more decimal places, providing higher precision. This is a key advantage of digital meters.
