Question
A narrow pipe in a water system is analogous to what concept in an electrical circuit?
Solution
A narrow pipe in a water system is analogous to resistance in an electrical circuit.
Here's the step by step explanation:
-
In a water system, water flows through pipes due to the pressure difference. The rate of flow of water is determined by the pressure difference and the size (diameter) of the pipe. A narrow pipe will restrict the flow of water.
-
Similarly, in an electrical circuit, electric current (analogous to the flow of water) flows due to the voltage difference (analogous to the pressure difference). The rate of flow of electric current is determined by the voltage difference and the resistance in the circuit.
-
Resistance (measured in ohms) is a property that determines how much current will flow for a given voltage. A high resistance will restrict the flow of current, just like a narrow pipe restricts the flow of water.
-
Therefore, a narrow pipe in a water system is analogous to a high resistance in an electrical circuit. Both restrict the flow (of water or electric current) for a given pressure difference (or voltage difference).
