Key Concepts

Total Circuit Resistance

Total circuit resistance is the sum of all resistive components in a circuit, including both the load resistance and any additional resistances such as that of the conductors. Keeping the conductor resistance as a small percentage of the total ensures that the voltage drop on the lines is minimal, delivering efficient power to the load.

Voltage Drop

Voltage drop refers to the reduction in voltage across a conductor or other electrical component due to its resistance. In any electrical system, a certain amount of voltage is lost as current flows through resistive elements, so controlling this drop is essential for proper operation of the load.

Conductor Resistance

Conductor resistance is the inherent resistance of the wiring in an electrical circuit. To minimize voltage drop along the line, the resistance of these conductors must be kept low relative to the total circuit resistance, ensuring that most of the supply voltage appears across the load.
