Question

Calculate the heat generated in the electric heater if the potential difference is 230 volt and power is 1000/2000 watt.​

Answer 1

Answer:

Given

V=230 volt

P=1000 W or j/sec

t=5 mit=5×60 sec

Heat produce, H=P×t

H=1000 j/sec×5×60 sec

H=300000 j

Answer 2

Answer:

given

v= 230 volt

P=1000 W or j/sec

t= 5min = 5/60 sec

heat produce H=p/t

H=1000 j/sec/5/60 sec

H=300000 j
