Which instrument can be used to measure DC/AC voltage, current, and resistance?

• A. Clamp Meter
• B. Multimeter
• C. Voltmeter
• D. Oscilloscope

Answer: (B)

A multimeter is a versatile instrument designed to measure various electrical parameters, including DC and AC voltage, current, and resistance. This multifunctionality is what sets it apart from other options. A multimeter typically features different settings or modes to measure each of these parameters accurately, making it an essential tool for electricians, technicians, and engineers.

In contrast, a clamp meter is primarily used to measure current and can also measure voltage, but it is not typically used for resistance measurements. A voltmeter is specifically designed for measuring voltage only, which limits its functionality compared to a multimeter. An oscilloscope is used for visually displaying voltage signals over time, and while it can measure voltage, it does not measure current or resistance in the way a multimeter does. Thus, the multimeter's ability to measure all three parameters makes it the most suitable choice for this question.
