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

(a) 1 and 10⁶

(b) 1,10³and 10⁶

(a) The equivalent resistance of two resistances 1and 10⁶ connected in parallel will be less than 1.This is because when a number of resistances are connected in parallel, then their equivalent resistance is less than the smallest individual resistance. Here, since the smallest resistance is 1. Therefore, the net resistance will be less than 1

(b) The equivalent resistance of three resistances1,10³and 10⁶ connected in parallel will be less than 1 because the smallest resistance is 1.
