Which of the following measurements are made using a multimeter?
Signal strength and noise
Impedance and reactance
Voltage and resistance✓Bonne réponse
All these choices are correct
Explication
A multimeter is the combination of a voltmeter, ammeter and ohmmeter in one instrument, so voltage and resistance are both directly on its function switch, along with current. It does not measure impedance, reactance, signal strength or noise, so the all-of-these choice is wrong.
