Question

Judge the equivalent resistance when the following are
connected in parallel :
(a) 10 and 10902 (b) 102,100 and 10°02​

Answer 1

Answer:

(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
