Solution

The correct option is B
1

In the figure, there are two parallel combination of resistors each having a value of $1 O h m$

$R_{p a r a l l e l}$ = $\frac{1 \times 1}{1 + 1}$ = $\frac{1}{2}$ for both of them.

Now, these resistors are in series.

$R_{s e r i e s} = 0.5 + 0.5 = 1 O h m$

So, the effective resistance is $1 O h m$ .

The correct option is B 1 In the figure, there are two parallel combination of resistors each having a value of 1 Ohm Rparallel = 1×11+1 = 12 for both of them. Now, these resistors are in series. Rseries =0.5+0.5=1 Ohm So, the effective resistance is 1 Ohm.
