Calculate the amount of heat produced in an electric heater of resistances 1000 ohms if 6A current is passed through it for 10 minutes.
Answers
Answer:
: 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

Answer:
Explanation:
Given,
Current (I) = 6A
Resistance (R) = 1000ohms
Time (t) = 10 minutes= (10*60)seconds = 600 seconds
we know,
heat produced= I^2Rt
= (6)^2(1000)(600)
= 36*1000*600
= 21600000 J
Therefore, the heat produced by the electric heater is 216*10^5 J
