In this video from LearnElectrics we will look at how we can find R1 for a circuit given minimal information; and show just what the differences in R1 and R2 are in Ring and Radial circuits.
We’ve had several requests from people that are taking electrical assessments and one of their questions asked them - How can I work out R1 if I only have R1+R2 for a circuit?
In this video we will use, as examples, a radial circuit and a ring circuit that are both the same length and both use the same size standard twin and earth cable. But because one is a radial circuit and the other is a ring circuit, some of the circuit values are different and you need to understand these; what the differences are, why they are different, and how to calculate circuit values with them.
These skills will not only help in exams and assessments, but they are also useful for certificate completion when on-site.
As always, when testing installations and circuits, follow the safe isolation procedure and work safely
