Quick Reference Guide; Library; Wire Connection Guide; Wire Size Calculator; Conduit Size Calculator; Selecting Transformers; Timer Compatbility; Voltage Loss Formulas; Maximum Allowed Wire Runs; Warranty; Contact; Store The area of electrical wire is measured in a unit called "circular mils.'' ρ = Specific resistance or resistivity of Conductor; D = Distance in Feet (One way) i.e.
Simple to use Ohm's Law Calculator. Online electrical resistance calculator to calculate resistivity of a wire using row value, length and area of wire. Just enter 2 known values and the calculator will solve for the others. Code to add this calci to your website Just copy and paste the below code to your webpage where you want to display this calculator. Set three, calculate the fourth. Example 1: Must calculate the resistance of a copper cable that has a cross-sectional area of 2.5mm2, temperature of … There is a specific formula you can use to calculate the resistance of copper wire based on its area and length. To save time, a calculator comes in handy to crunch the numbers. Calculate Power, Current, Voltage or Resistance. If you just want a calculator that is simple to use, and you don't make mixed wires, the old coil wrapping calculator is probably a better choice for you. The AWG is a logarithmic scale, so given an know resistance or diameter for a certain gauge, you can quickly figure out the resistance and diameter of another gauge number, by addition and subtraction. Wire Resistance & Properties; Wire Size Conversion (AWG/Metric) Resources. Each affects the others.

Round Wire ac Resistance Calculator. There are four variables involved in determining what you need: voltage, gage, length, and temperature. ½ the total circuit length; I = Load Current; Note: the Value of ρ = Specific resistance or resistivity of Conductor is used here for copper and aluminum is 11.2 and 17.4 respectively at 53° C (127° F) Online calculator for calculating properties of a round wire. AWG American Wire Gauge Diameter and Resistance. Calculates the ac resistance of a round straight wire for common conducting materials using the equation and data referenced below or by manually entered material data.
The wire you have built has a resistance factor of at this temperature. Use this calculator to find the right nichrome wire size, length and power supply for your application.
