Question

A heater at 220v boils a volume of water in 5 minutes

Answer 1

Hi friend,

We know that

H=V²R/t

H.α v²/t

V²1/t1 = v²2/t2

(220)²/5=(110)²/10n

4/1 =1/2n

n=1/8.

Hope this helped you a little!!!

Answer:

No it will take 2 minutes or more. you can use this formula for your answer H=v2R/T
