Judge the equivalent resistance when the following are connected in parallel : (i) 1 Ω and 106 Ω, (if) 1 Ω and 103 Ω and 106 Ω.

When the resistances are connected in parallel, the equivalent resistance is smaller than the smallest individual resistance. (i) Equivalent resistance < 1 Ω. (ii) Equivalent resistance < 1 Ω.
