1. The problem statement, all variables and given/known data https://z-1-scontent-sin1-1.xx.fbcdn.net/hphotos-xtf1/v/t34.0-12/12435980_942112312550457_1708451532_n.jpg?oh=b29a5e9b2ff96bbf0e11932d081eb25e&oe=568A9B79 We need to find the equivalent resistance along A to B ie AB 2. Relevant equations R=(1/R1 + 1/R2+.........+1/Rn)^-1 , Y-Delta transformation , equation for parallel combination, equation for series combination. 3. The attempt at a solution I tried wye-delta but my teacher says that I need not use wye-delta .How possible? I have two answer 1.43 ohms and 1.6 ohms .What is the actual equivalent resistance? Can you please solve these problems?
