Imagine a water hose system where water flows through a hose.
-
Voltage: Voltage is like the water pressure in the hose. Just like high water pressure causes water to flow faster and with more force, higher voltage causes electric current to flow more easily in a circuit.
-
Current: Current is like the amount of water flowing through the hose. It represents the quantity of electric charge flowing in a circuit per unit of time. Just as a larger hose can allow more water to flow through, a lower resistance in a circuit allows more current to flow.
-
Resistance: Resistance is like the tightness or narrowness of the hose. A hose with higher resistance would make it harder for water to flow through. Similarly, a component with higher resistance in a circuit restricts the flow of electric current.
In summary, voltage is the pressure pushing the electric current (water) through the circuit (hose), current is the flow rate of the electric charge (water), and resistance is the obstruction that hinders the flow of electric current.
