Question

5ampe.current passes through for 2 hour an electric iron with resistance 100 ohm . calculate heat loss. ..???

Answer 1

here is the answr.................

Answer 2

Current(i)=5 A
Resistance(R
r) =100 ohm
Time(t)=2 hr
$heat \: loss = i {}^{2} rt$
=5×5×100×2=5000Wh=5kWh
Hope this helps : )
