Resistance is defined as

Resistance is the opposition to the flow of electric current in a circuit. It acts like a resisting force on moving electrons as they travel through a material, because collisions and interactions with atoms slow them down. For a given voltage, higher resistance means a smaller current, which is why Ohm’s law uses R = V / I. The option describing resistance as the force resisting motion in a circuit best captures this idea of opposition to current flow. The other ideas describe energy output, or the rate at which energy is transformed or transferred, which relate to power, not resistance.
