Hello everyone

The question is to find the equivalent resistance of the diagram.

I have redrawn the diagram but it did really not help since I am not sure how to deal with the interconnecting parallels.

Now if I made a mistake with the redrawn diagram please correct me.

Please give hints or any sorts of help if possible.

Thanks.

 

The redrawn diagram is correct.

Hint:the 12R is in parallel with the 25R. The 12-25 parallel combination is in series with the 4.5R.

Think of the rest.
