Calculate the amount of heat produced in an electric heater of resistance 1000 ohms if 6 a current is passed throught it for 10 minutes.
solution : resistance of electric heater , R = 1000 ohms.
current through electric heater , I = 6A
time taken to pass current through it,t = 10 minute = 600 sec
we know,
amount of heat produced in electric heater = i²Rt
= (6A)² × 1000ohms × 600s
= 36 × 600000 J
= 21600000 J
= 2.16 × 10^7 J
hence, answer should be 2.16 × 10^7 J
