Question

An electric iron .........

Answer 1

An electric iron is a good conductor

Answer 2

hi buddy Merry Christmas Here is ur answer

give that Rinstance =20 Ohm

electric current (I ) = 5A

Now we know that, H,= 1 ^2 RT

Time (t) = 30 sec

= 5 x 5 x 20 x 30

= 15000 j = 1.5 x 10 ^ 4 J

Therefor ,

the heat developed is 30 second in 1.5 into 10 ^ J
