Calculate the equivalent resistance when two resistances are connected in parallel of values 2 Ω, 2 Ω.(a) 1 Ω(b) 2 Ω(c) 4 Ω(d) 7 ΩThe question was asked in examination.This question is from Electric Motors in division Braking of Electric Motors of Electric Drives

Answer»

Correct option is (a) 1 Ω

The best I can EXPLAIN: When two RESISTANCES are connected in parallel their equivalent resistance is equal to the HARMONIC mean of the individual resistances. Req=R1.R2÷(R1+R2)=22 Ω.
