Question: 1 / 455

What happens to the voltage drop along a conductor as its length increases?

Increases

As the length of a conductor increases, the voltage drop along that conductor also increases. This relationship can be attributed to the inherent resistance of the conductor material. The longer the conductor, the more resistance it presents to the flow of electric current. According to Ohm's Law, voltage drop is directly proportional to both the current flowing through the conductor and its resistance.

Therefore, if the length of the conductor is increased, its resistance increases, which in turn leads to a greater voltage drop when the same current is passing through it. This principle is fundamental in electrical system design, as it highlights the importance of using appropriately sized conductors to minimize voltage drop over long distances, ensuring efficient power delivery and performance of electrical devices.
