What type of meter is referred to as an analog meter with a needle?

• A. D'Arsonval meter
• B. Digital multimeter
• C. Clamp meter
• D. Solid state meter

Answer: (A)

An analog meter with a needle is indeed referred to as a D'Arsonval meter. This type of meter operates on the principle of electromagnetic deflection, where the current flowing through a coil creates a magnetic field that causes the needle to move against a calibrated scale. This provides a visual indication of the measurement being taken, such as voltage, current, or resistance. In contrast, a digital multimeter displays its readings on a digital screen, making it fundamentally different from the analog type. A clamp meter, while used to measure current, typically has jaws that clamp around a conductor and displays the measurement digitally or via a needle in some older models. Solid state meters use electronic components and circuits for measurement, rather than relying on the mechanical movement of a needle. Thus, the D'Arsonval meter stands out as the key example of an analog meter with a needle that accurately indicates varying electrical measurements.
