Question

A conductor with rectangular cross-section having dimensions a × 2a × 4a as shown in figure. If the resistance across AB is R₁, across CD is R₂ and across EF is R₃, then the ratio R₁ : R₂ : R₃ is

चित्र में विमाओं a × 2a × 4a वाला आयताकार अनुप्रस्थ-काट का एक चालक दर्शाया गया है। यदि AB के सिरों पर प्रतिरोध R₁ है, CD के सिरों पर प्रतिरोध R₂ है तथा EF के सिरों पर प्रतिरोध R₃ है, तब अनुपात R₁ : R₂ : R₃ है
