When a known standard resistor of 2 $Ω$ is connected to the 0.0cm end of a meter bridge, the balance point is found to be at 55.0cm. What is the value of the unknown resistor?

1.10

Ω

1.64Ω

2.44

Ω

27.50

Ω

Answer Details

$\frac{R_{1}}{R_{2}}$ = $\frac{L_{1}}{R_{2}}$

$\frac{2}{R_{2}}$ = $\frac{55}{45}$

R =1.64 $Ω$
