A device which can measure current, potential difference and resistance accurately is called:
Correct answer: C. AVO meter
- A. Ammeter
- B. Voltmeter
- C. AVO meter
- D. Ohm meter
Explanation
AVO meter is a combined instrument that can measure current (amperes), potential difference (volts), and resistance (ohms). It integrates the functions of both ammeter and voltmeter, and in addition, it includes a resistance measurement function. AVO meters are versatile tools commonly used by electricians, technicians, and hobbyists for various electrical measurements in circuits.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
