The function of resistors in distribution boxes
One of the primary functions of resistors is to limit the flow of electric current. By introducing a resistor with a specific resistance value into a circuit, the current can be controlled according to Ohm's Law (V = I × R), where V is voltage, I is current, and R is resistance. Their role in controlling, managing, and dissipating electrical energy is fundamental to system safety, reliability, and performance. Core Functions: Managing More Than Just Resistance Power resistors are not just about “resisting” current—they're designed to handle high wattage and perform. The distribution box (DB box) helps safely and efficiently distribute electrical power. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage.
