The amount of heat energy generated from the electric iron is of 59389.2 J.
Given data:
The potential difference of the source is, V' = 110 V.
The amount of current drawn is, I = 9 A.
The time interval is, t = 1 min = 60 s.
The current flow through the the electric iron produces the heating effect, and the expression for the heat energy generated in a given time is,
[tex]H=I^{2} \times R \times t[/tex]
Here, R is the resistance of electric iron and its value is calculated as,
[tex]V=IR\\\\R=\dfrac{V}{I}\\\\R=\dfrac{110}{9}\\\\R=12.22 \;\rm \Omega[/tex]
So, the heat energy generated is,
[tex]H=(9)^{2} \times 12.22 \times 60\\\\H = 59389.2 \;\rm J[/tex]
Thus, we can conclude that the amount of heat energy generated from the electric iron is of 59389.2 J.
