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. This is why rubbing two sticks together will eventually produce a fire.

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. There is no mystery behind friction. It acts on objects at the surfaces so as to prevent or reduce movement between the surfaces.

4. The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.

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
