This is how the varley bridge circuit looks. I just cannot see which of my existing formulae or how to create a new to show Rl=RcAcLl/AlLc

Homework Statement A Varley Bridge is connected to a faulty three-core copper cable by two identical copper leads of resistance Rl. (a) Show that for the initial reading (connection to earth); 2Rx = 2Rc – Ri ........ 1 where Rc is the resistance of the cable core Ri is the initial reading...
