What is the formula for power cable impedance?
I = current flowing in cable, in amperes. Zc = impedance of cable, in ohms. = ¡î(R2c + X2c)
How to find the impedance of a cable?
To calculate impedance, calculate the resistance and reactance of the circuit, then label resistance as R and reactance as X. Square both R and X, and add the two products together. Take the square root of the sum of the squares of R and X to get impedance. Display the answer in ohms.
What is the meaning of impedance of a wire?
Impedance is measured in Ohms and represents the total resistance that the cable presents to the electrical current passing through it. Impedance is associated with AC circuits.
How to calculate cable resistance and reactance?
Step 1: Identify the resistivity , length (L), and radius (r) of the wire. Step 2: Calculate the cross-sectional area of the wire using the formula for the area of a circle: A = ¥ð r 2 . Step 3: Calculate the resistance (R) of the wire using the formula for resistance: R = ¥ñ L A .
