Four wires of equal length and of resistance $5 Ω$ each are connected in the form of a square. The equivalent resistance between the diagonally opposite corners of the square is

Options:

Answer:

Solution:

The equivalent resistance of branch $A P B,$

$R_{1} = 5 + 5 = 10 Ω$

The equivalent resistance of branch $A Q B,$

$R_{2} = 5 + 5 = 10 Ω$

As $R_{1}$ and $R_{2}$ are in parallel,

$∴ R_{e q} = {\frac{R_{1} R_{2}}{R_{1} + R_{2}}}_{}$

$R_{e q} = {\frac{(10) (10)}{10 + 10}}_{}$

$R_{e q} = 5 Ω$
