The resistance of metal sheet $1$ between $A$ and $B$ is $R_{1}$ and the resistance of sheet $2$ between $A'$ and $B'$ is $R_{2}$ . The value of the ratio $\frac{R_{1}}{R_{2}}$ is

Options:

Answer:

Solution:

For Sheet 1 resistance is,

$R_{1} = \frac{ρ l}{l t} = \frac{ρ}{t}$

For Sheet 2 resistance is,

$R_{2} = \frac{ρ 2 l}{2 l \times t} = \frac{ρ}{t}$

$∴ \frac{R_{1}}{R_{2}} = 1$
