Questions
Two resistances R1 and R2 when connected in series and parallel with 120 V line, power consumed will be 25 W and 100 W, respectively. Then the ratio of power consumed by R1 to that consumed by R2 will be
detailed solution
Correct option is A
P=V2R ⇒ PPPS = RSRP=R1+R2R1R2 / R1+R2 =R1+R22R1R2⇒ 10025 = R1+R22R1R2 ⇒R2R1 = 11Talk to our academic expert!
