Question 1:

Judge the equivalent resistance when the following are connected in parallel −

(a) 1 Ω and 10⁶ Ω,    (b) 1 Ω and 10³ Ω and 10⁶ Ω.

Answer:

(a) When 1 Ω and 106 Ω are connected in parallel:

Let R be the equivalent resistance.

Therefore, equivalent resistance ≈ 1 Ω

(b) When 1 Ω , 10³ Ω, and 10⁶ Ω are connected in parallel:

Let R be the equivalent resistance.

Therefore, equivalent resistance = 0.999 Ω
