What does a multimeter measure?
- A SWR and power
- B Voltage, current and resistance
- C Resistance, capacitance and inductance
- D Resistance and reactance
Correct answer: B — Voltage, current and resistance. From the official ISED question bank, verified word for word.
Why
A multimeter is a versatile tool designed to check the three fundamental properties of electricity: voltage, which is the electrical pressure; current, the flow of charge; and resistance, how much a material opposes that flow. The full explanation — and one for every question — is in Pro.
