Divide the voltage drop by the current. According to BS 7671 – TABLE 4Ab and IEC60364-5-52, article 525, table G. Calculate voltage drops with ease by inputting source voltage, current, distance (in feet, meters, centimeters, or inches), and wire resistance (in ohms/1000ft, milliohms/1000ft, or microohms/1000ft). Follow these steps to calculate it: Determine the electric current I (i. Solving voltage drop on 12V DC on longer runs / product recommendation. ; Z c is the wire impedance in Ω/km. Reactance is the opposition offered by the capacitor to the AC voltage. Ohm's Law, used to calculate the voltage drop in a circuit, was named after German physicist and mathematician Georg Simon Ohm who published the formulation in 1827. If the calculated voltage drop is greater than 0. The left column notes the amount of power that the device you are powering requires .
