Resistance determines how much current will flow through a component. Resistors are used to control voltage and current levels. A very high resistance allows a small amount of current flow. A very low resistance allows a large amount of current to flow. The resistance to a flow of water through a hose would be termed friction loss and would be measured in pounds per square inch.
