Friction reduces the flow of water through a pipe like ____ reduces the flow of electricity through a wire.

Friction reduces the flow of water through a pipe like ____ reduces the flow of electricity through a wire.

• A. Voltage
• B. Resistance
• C. Power
• D. Capacitance

Answer: (B)

Friction is a force that opposes the movement of water through a pipe, much like resistance opposes the flow of electricity in a circuit. When water moves through a pipe, the friction between the water and the pipe walls slows down the flow, reducing the overall velocity and creating a loss of pressure. Resistance in electrical terms serves a similar purpose by impeding the flow of electric current. Higher resistance in a wire means that less current will flow for the same applied voltage, thereby controlling the flow of electricity through the circuit. In both cases, the concept revolves around the idea of an opposing factor—friction for water flow and resistance for electrical flow—making the relationship clear and applicable to fluid mechanics and electrical engineering alike. The other options, like voltage, power, and capacitance, do not directly relate to this analogy as they define different aspects of electrical systems and do not serve the same purpose in reducing flow.
