Question

Three resistors with magnitudes 20Ω, 4Ω and 80Ω are connected in parallel, then equivalent resistance of the system would be

(a) less than 2Ω

(b) more than 2Ω but less than 4Ω

(c) 4Ω

(d) 14Ω

Answer 1

(a) less than 2Ω

Equivalent resistance of three resistors of resistances 2Ω, 4 Ω and 8Ω,

Therefore, equivalent resistance is less than 2Ω
