Hello everybody hope this trick used by me for star-delta conversion proves helpful to you too:
We are taking here a star connection and making its delta counterpart

Just number the end points of connection. For example just as I did in this shown figure.

Now just draw the corresponding network dat is if you are converting star to delta draw a delta network outside the star network. As shown in figure.

Now jsut use the formula. For using the formula there is a simple trick

see the numbers in subscript dat is 1 & 2 shud be written like this and divided by third resistance.

For converting delta to star repeat the same steps but change the formulae

 you d'nt have to mug up the formulae just point it out datas we are finding out R1 the resistances in top part are all having 1 as subscript(R12 & R31 or R13) and at the bottom
there is sum of all three resistance dat is (R12+R23+R31)
