Hello friends, I hope you all are doing great. Today, I am going to share the new Power Resistor Library for Proteus . A small resistor on a board handles a quarter of a watt or less. But some jobs need far more: a load to test a power supply, a resistor to drop a motor's current, a brake for a stepper drive, or a heater. For those jobs you will find a chunky white block with two wire legs and its value printed on the side, the cement resistor , and it is one of the toughest parts in electronics.
