Answer 1

Thanks for asking

Hope it will help

Answer 2

According to the Ohm's law,

To calculate the heat produuced in a circuit by different conductors of the resistance we have to apply the formula written below,

Amount of Heat;

H= (I^2) * R * t

So,

1)H=(I^2) * R * t =(I^2)*2r*t

2)H=(I^2) * R * t =(I^2)*r*t

So the ratio will be,

=2:1 (ans)
