Current, Voltage, and Resistance

These three are related by a very simple equation:

Take a minute and reflect on the relationship between these three components. Think of it like it's a garden hose:

The current is water flowing in the hose. The water pressure is analogous to the voltage of a circuit and the diameter of the hose determines the resistance.

happens when you put a nozzle on end of the hose? In this case, the resistance increases with a constant amount of water flowing through it. What happens to the pressure?
