Answer:
1.Resistance is a measure of the opposition to current flow in an electrical circuit
2.For instance, when two objects rub together, friction causes some of the energy of motion to be converted into heat, according to the American Chemical Society.
3.Rough surfaces have more friction than smooth surfaces and liquids such as oil or water are sometimes used as lubricants to reduce the effect of friction.
4.The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.
5.Making a surface rougher or smoother may not always affect the sliding friction. In addition to this, for certain textures and materials, making a surface smoother reduces friction. But elsewhere, rougher surfaces can actually have less friction.
