Resistance is the property of a material that _______.
-
A.
allows the flow of current
-
B.
opposes the flow of current
-
C.
generates electricity
-
D.
converts electrical energy to mechanical energy
Correct Answer:
B. opposes the flow of current
Explanation:
The correct answer is Option B: opposes the flow of current.
Electrical resistance is a fundamental characteristic of a substance that hinders or obstructs the movement of electric charges through it. When electrons travel through a conductor, they collide with the material's atoms, which creates this opposition. Higher resistance indicates that it is more difficult for current to pass through, whereas lower resistance allows for easier flow. This property is measured in ohms and is essential for controlling the amount of current in various electrical circuits and components.
