Question

A heating element using nichrome connected to a 230 v supply draws an initial current of 3.2 a

Answer 1

H=i^2Rt ( we know V=iR)
H = VIt
therefore,

H/t = Vi
= 230×3.2
= 736 Joule.

so heat element is equal to 736 joule

Answer 2

Hi friend,

Myself saka here to help you out!!!!

Formula:-

H = VIt

Calculations:-

H/t = Vi
= 230×3.2
= 736 J

Result:-

736J

Hope I helped you a little!!!
