1) An oven takes 16A at 220 V. It is desired to reduce the current to 12A. The value of resistance wil be

A)4.58Ω
B) 6.2Ω
C)7.1Ω
D) 10Ω

Show Answer

A) 4.58Ω
Exp-: R₀=v/i 220/16=13.75Ω (R₀ is the No load resistance of the circuit) Now this is no load resistannce of oven and we have to find the value of resistance after reduce its current to 12A now apply formula R=V/I-R₀ 220/12-13.75 Now you get this value 4.58Ω
