Parallel combination of resistors

The voltage is same across each circuit element is same but current is different & is inversely proportional to resistance of that part.

V = V₁ = V₂ = V₃ = I₁R₁ = I₂R₂ = I₃R₃

&

Fact the maximum number of combination one can have, using all n – resistors at a time is:

(a)  2 (n – 1)      [For n – identical resistors

(b) 2ⁿ                    For n – different resistors
