Question

Resistance of metal sheet 1 between shaded portion is R₁ and Resistance between shaded portion for sheet 2 is R₂ the R₁/R₂ is –

• A. 1
• B. 1/2
• C. 2
• D. 4

Answer 1

Answer: (A)

1

Answer 2

R₁ = $\frac{\rho\mathcal{l}}{\mathcal{l}t}$ = ρ/t R₂ = $\frac{\rho 2\mathcal{l}}{2\mathcal{l \times}t}$ = ρ/t ∴ R₁/R₂ = 1
