Which one of the following quantities is not measured by avometer?
Correct answer: A. Charge
- A. Charge
- B. Current
- C. Resistance
- D. Potential difference
Explanation
An avometer (multimeter) can measure current, resistance, and potential difference, but it does not directly measure electric charge. Charge measurements usually require other specialized instruments or methods.

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.
