EASY VOLTAGE DROP FORMULA and CABLE SIZE CALCULATIONS – ALL IN ONE - NO BOOKS – NO TABLES

We’ve been asked by many times if the voltage drop formulas can be made any easier.
Some say that the tables just confuse them, there is too much going backwards and forwards in the book and so on.
So what we will do in this video is what is called formula manipulation.
We will show you how to combine some different formulas that we might already know into just one formula that works better for us and is easier to use. Especially as this method uses no books or tables.
Everything is self-contained within the formula that we show you.
