Calculate the equivalent resistance when three resistances are connected in series of values 8 Ω, 3 Ω, 1 Ω.(a) 12 Ω(b) 18 Ω(c) 15 Ω(d) 16 ΩThis question was posed to me in examination.My query is from Electric Motors in division Braking of Electric Motors of Electric Drives

Answer»

The correct choice is (a) 12 Ω

The BEST I can explain: When three resistances are CONNECTED in series their EQUIVALENT resistance is equal to the sum of the INDIVIDUAL resistances. Req=R1+ R3+R2=12 Ω.
