Which of the following can be used to measure electrical resistance?

A multimeter is a versatile instrument used in electrical measurements, and it is specifically designed to measure various electrical parameters, including voltage, current, and resistance. To measure electrical resistance, a multimeter functions by passing a small known current through a resistance and measuring the voltage drop across it. According to Ohm's Law (V = IR), the resistance can then be calculated by rearranging the formula to R = V/I, where R is resistance, V is voltage, and I is current. This capability makes the multimeter a fundamental tool in both automotive and electronics troubleshooting, where determining the resistance of components is essential for diagnosing issues.

While oscilloscopes, capacitor meters, and power meters serve important functions in electrical measurements, they do not have the capability to measure resistance directly. An oscilloscope is primarily used for visualizing waveforms of electrical signals. A capacitor meter is specifically designed to measure capacitance rather than resistance. A power meter measures electrical power in watts, dealing with the rate of energy consumption but not focusing on resistance. Thus, the multimeter's design and functionality make it the appropriate and effective choice for measuring electrical resistance.
