Resistance (R) is a force that resists the flow of current, which is present in all materials and all electrical systems. It is measured in Ohms (Ω). If the wires in an electrical circuit are too small for the amount of current that they need to carry, it will create friction and heat. Voltage is lost as a result. Similarly, the pipes through which the water flows in the water system can create friction if there is too much pressure or volume trying to pass through them.
