PhysicsEasysingle choice

The resistance of metal sheet 1 between the shaded portion is $R_{1}$ and Resistance between shaded portion for sheet 2 is $R_{2}$ the $R_{1} / R_{2}$ is

Options:

Answer:

Solution:

Resistance = $\frac{R e s i s t i v i t y \times L e n g t h b e t w e e n t w o f a c e s}{A r e a o f t h e f a c e}$

$R_{1} = \frac{ρ l}{l t} = \frac{ρ}{t} R_{2} = \frac{ρ 2 l}{2 l \times t} = \frac{ρ}{t}$

$∴ R_{1} / R_{2} = 1$
