Answer:
The diagram indicates a square ABCD formed by joining four resistances of 2Ω each, end to end. ...
From figure, arms DA, AB and BC are joined in series.
So, their equivalent resistance = (2 + 2 + 2)Ω = 6Ω
Now resistance of 6Ω and 2Ω are in parallel.
∴ The equivalent resistance of the combination is R.
