Question

If 3A current flows through a electronic iron which is designed to work at 230V for 10s calculate heat energy generated using the following equation.
$h = {i}^{2} rt$


​

Answer 1

V=230 V

I=3 A

t=30 m=30×60=1800 s

H=VIt=230×3×1800=1242000 J=1242 kJ

hope this helps you !! brainliest please
