Technician exam question T7D07
Subelement T7, PRACTICAL CIRCUITS· Group T7D
Which of the following measurements are made using a multimeter?
- A.Signal strength and noise
- B.Impedance and reactance
- C.Voltage and resistance (correct answer)
- D.All these choices are correct
WhyA multimeter is used to measure voltage and resistance. A multimeter is built to measure voltage and resistance (and typically current as well), the basic electrical quantities in a DC circuit, answer C. Signal strength and noise (A) are measured with instruments like an S-meter or spectrum analyzer, and impedance and reactance (B) require AC test equipment beyond a basic multimeter's simple DC measurements, so D, which depends on all of those being multimeter functions, is also wrong.
