Power rating $P=750W$

Rated voltage $V=220V$

$(i)$ We know $P=VI$

$750=220×I$

$⇒$ $I=220750 =3.40A$

$(ii)$ Also, power can also be wriiten as

$(i)$ We know $P=VI$

$750=220×I$

$⇒$ $I=220750 =3.40A$

$(ii)$ Also, power can also be wriiten as

$P=RV_{2} $

$⇒$ $R=PV_{2} =750220_{2} $

$⇒$ $R=PV_{2} =750220_{2} $

So resistance of electric iron $R=64.53Ω$
