Opposition of flow of electric current is called:A) Potential difference.B) Electric charge.C) Resistance.D) Electromagnetic induction.

The correct answer is C) Resistance.

Explanation:

Potential difference is the difference in electric potential between two points, which causes the flow of electric current. It is not the opposition to the current flow.
Electric charge refers to the property of particles (such as electrons) that causes them to experience a force in an electric and magnetic field. It does not oppose the current flow.
Resistance is the property of a material or component that resists or opposes the flow of electric current. It is measured in ohms (Ω) and depends on the material, temperature, and dimensions of the conductor.
Electromagnetic induction is the process by which a changing magnetic field induces an electromotive force (EMF) in a conductor. It is not related to opposition of current flow.
Thus, the correct term for the opposition of electric current flow is resistance.
