An instrument, which can measure potential without drawing any current, is

Correct answer: A. Voltmeter

  • A. Voltmeter
  • B. Galvanometer
  • C. Cathode Ray Oscilloscope (CRO)
  • D. Ammeter

Explanation

An instrument capable of measuring potential without drawing any current is:A voltmeter is designed to measure the potential difference between two points in an electrical circuit. It's constructed to have a very high resistance, allowing it to measure voltage without drawing any significant current through the circuit.Possible Correct Answer:(a) Voltmeter

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.
