Question

Refind heat 230 volt 460 ohm 10 minutes

Answer 1

So ,

Before commencing the solution it is conspicuous that V = 230V , R = 460 OHM
T = 10 MINS. SO It is evident from the fact that
I = V / R , I = 230 / 460 , I = 1 / 2 A .

SO HEAT FORMULA IS GIVEN LIKE THIS :-

HEAT =
${i}^{2} rt$
BY SUBSTITUTING THE VALUES OF I , R AND V IN RESPECTIVE VALUES , WE GET ,

(1/2)^2 × (460) × (10 × 60)

= (1/4) × (460) × (600)

= BY UNRAVELLING THIS SIMPLIFICATION WE GET ,

= 1 × 460 × 150

= 69 , 000 JOULE


SO YOUR ANSWER IS 69 , 000 JOULE.
