The amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm. Using Ohms Law, this gives us a flow (current) of 1 amp. Using this analogy, let''s now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher.
