Star delta transformation
in this delta diagram R12 lie between 1 and 2 ,R23 lie between 2 and 3 ,R31 lie between 1 and 3.
NOTE – Star is also know as (T) and delta is known as (∏)
First let us check out the delta to star conversion:-
Now The Solution :- R1= R13 × R23/R13 + R23 + R12 R2 = R12 × R13/R13 + R23 + R12 R3 = R23 × R12/R13 + R23 + R12
Now the solution ÷ R31 = R1 + R3 + (R1 ×R3/R2) R12 = R1+ R2 + (R1 × R2/R3) R32 = R3 + R2 + (R3 × R2/R1)
