Question

An electric oven of resistance 20 ohm takes a current of 5 ampere calculate the heat developed in 30 seconds

Answer 1

R=20 ohm

I=5 A

t=30 s

H=I^2 R T

  =5^2*20*30

   =15000J

    =15 KJ

PLEASE MARK AS BRAINLIEST

Answer 2

Given :-

R = 20 Ω

I = 5 A

t = 30 s

H = I^2Rt

= (5)^2×20×30

= 15000 J

= 1.5 × 10^4 J
