Question

a water heater of resistant 1,000 ohm is connected across a mainly supply of 220 volt determine the current through the element of the heater also calculate the amount of heat produced in kilojoule in 1 hour​

Answer 1

Answer:

174.24 kj

Explanation:

R=1000 ohm

V=220v

then current I=V/R=220/1000=.22A

Heat produced H=VIt=220*0.22*3600

                          =174240 jool =174.24 kj
