PEC has designed, manufactured, and delivered resistors to global customers for 50 years. We have a comprehensive range of power resistors for use in Industrial, Automotive, Traction, Power Systems, Medical Equipment, Renewable Energy, Electric Vehicles, Aviation and Military applications.
This resistor calculator converts the ohm value and tolerance based on resistor color codes and determines the resistances of resistors in parallel or series.
PEC has been at the forefront of developing custom resistors solutions for our global and India customers. In most critical applications, a degree of customization is required to handle field electrical & physical usage conditions.
This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.
Use DigiKey’s Ohm’s Law calculator to calculate the relationships between current, voltage, resistance, and power in simple resistive circuits. Enter at least any two input values and click calculate to solve for the remaining values.
The resistor color code calculator makes it easy to identify and select resistance and tolerance values for 4, 5, and 6 band through hole resistors.
These tools allow you to determine the ohm value and tolerance using resistor color codes, calculate the total resistance when resistors are connected in parallel or series, and even estimate conductor resistance based on size and conductivity.
