In the given figure switches $S_{1}$ and $S_{2}$ are in open condition. The resistance across $a b$ when the switches $S_{1}$ and $S_{2}$ are closed is ________ $Ω .$

Question diagram: In the given figure switches S 1 and S 2 are in open conditi

Answer:

10.00

Solution:

when switch $S_{1}$ and $S_{2}$ are closed

$(\frac{12 \times 6}{12 + 6}) + 2 + (\frac{6 \times 12}{6 + 12})$

$\frac{72}{18} + 2 + \frac{72}{18} = 4 + 2 + 4 = 10 Ω$
