Question

Determination of activity coefficient from emf measurement

Answer 1

Explanation:

Ans: (a) Since 1 Ω and 106 Ω are connected in parallel then the equivalent resistance R will be

∴

⇒ R = ≈=1 Ω

∴ Equivalent resistance is 1 Ω

(b) 1 Ω and 103Ω and 106Ω are in parallel

∴

∴

∴ ⇒ R = 0.999 Ω

Therefore, equivalent resistance = 0.999 Ω
