Question
Six resistors, each of value 3
are connected as shown in the figure. A cell of emf 3V is connected across 
The effective resistance across 
and the current through the arm will be
- 0.6, 1 A
, 2 A
,2 A
- 1.5
, 1 A
, 1 A
, 2 A
,2 A
, 1 A
The correct answer is: 1.5 , 1 A
The equivalent circuit is shown as
We can emit the resistance in the arm DF as balance condition is satisfied.
Therefore, the 3 resistances in arm CD and DE are in series.
Similarly, for arms CF and FE, R’’=6
are in parallel
R’’’=3
Now, R’’’ and 3 resistances are in parallel
Moreover, V across AB=3V and resistance in the arm=3
∴ Current through the arm will be
