RING CIRCUIT CALCULATIONS - TESTING METHODS AND SOME PROBLEMS – THE RIGHT NUMBERS AND THE WRONG ONES

This video is about ring circuit testing and the calculations. As well as the correct way to understand the calculations we will also show you some of the problems that may be encountered during the testing process. We also hope to show you how to recognise what are good readings and which numbers are the wrong ones. Many times over many years, people have told us at Learn Electrics that they know how to test a ring circuit, but they are never sure of the numbers, where the numbers come from and why it is so important to know what R1 plus R2 should be. And then, how do we measure it, can we calculate it, and why divide by 4, what is all that about. So we will look at what good readings should be and how to calculate them and then look at some wrong readings for a ring circuit test. How do you know when the numbers just don’t add up.
