The analogy is the flow of water. Just as water needs a pressure difference to flow, charges in a copper wire flow only with an electric potential difference.
What is the analogy used to explain the flow of electric charge, and how is it similar to the flow of water?

The hydraulic analogy is often employed to explain the flow of electric charge. In this analogy, electric current is likened to the flow of water in pipes. Voltage corresponds to water pressure, current to the rate of water flow, and resistance to pipe friction. Just as water flows from high to low pressure, electrons move from higher to lower voltage. Similarly, resistance opposes the flow, akin to friction in pipes. The analogy aids in conceptualizing electrical phenomena, drawing parallels between fluid dynamics and the behavior of electric charge, facilitating understanding of concepts like Ohm’s Law and circuit dynamics.
