Question

multiple choice question
electrical resistance (r) is the property of
o electrons casting off the charge associated with them
o inertia that must be overcome to decrease an electric current
o opposing or reducing a current

Explanation:

Electrical resistance is a fundamental property in physics. It is defined as the property of a material or component that opposes or reduces the flow of electric current. Electrons do not "cast off" charge in the context of resistance. And resistance is not related to inertia in the way described in the second option.

Answer:

opposing or reducing a current
