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

As the length of a conductor increases, the voltage drop along it also increases. This phenomenon is primarily due to the resistive properties of the conductor material, which causes energy loss in the form of heat as electrical current flows through it. The resistance of a conductor is directly proportional to its length; therefore, longer conductors have higher resistance, which leads to a greater voltage drop when a current is passed through them.

Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R), underlines this relationship. As the length of the conductor increases, resistance increases, resulting in an increased voltage drop for a given current. Hence, the correct understanding is that with longer conductors, there is a more significant voltage drop due to a higher total resistance within the circuit.
