What is the best analogy for voltage in an electrical circuit? (2023)
Step 1: Imagine a water tank that is filled with water. The height of the water in the tank represents the voltage in an electrical circuit.
Step 2: The higher the water level in the tank, the more potential energy it has to flow downwards. This is similar to how higher voltage means more potential energy for electric current to flow.
Step 3: When you open a tap at the bottom of the tank, the water flows out due to gravity. In an electrical circuit, when a circuit is closed, the current flows due to the voltage pushing it.
Step 4: If the tank is low on water (low voltage), not much water can flow out. Similarly, if the voltage is low, the current flow in the circuit will also be low.
