Question

write joules law of heating. what is the resistance of 1000 W , 220 V toaster.

Answer 1

Answer:

according to joules law of heating this law states that the heat produced in a resistor is

1)directly proptional to the square of the current for a given resistance

2)directly proptional to the resistance for a given current

3)Directly Proptional to the time for which the current flows through the resistor

H=I^RT

and the ressistance of above question is 48.5 ohm
