How to calculate thevenin's equivalent resistance

[hussain bani]

when i short the batteries to find the rth, i can't get whether is should put delta to star transformation to find thevenines resistance?
can some one tell me how to calculate thevenines equivalent resistance in the figure shown... step by step

It would help if there were actually a figure

Am uploading this word file it contains the image..:-)

Why do you think you need a delta/star transform? You have simple series and parallel resistors. The problem reduces to an extraordinarily simple one. You should try redrawing the circuit with the supplies shorted out.

so whT WILL BE nswer after shorting them and finding thevenine equivalent reistance across terninal a and b?
mine is coming 1.33 ohms, is it rite?

Yes. See how easy that was?

i solved 4 and 2 in parallel, and 10 parallel with ze0r, so automatically ans is 0 of 10 iin parallel with zero, so the only thing left was 4 in parallel with 2, that's is 1.33.
this is correct method right?
