The heat current across a certain cinductive material is H. If the cross-sectional area of the material is tripled and everything else remains the same, how is the heat current affected?

Answer:

Resistance is inversely proportional to the cross section area of the material, hence when cross sectional area is tripled, also resistance triples.

Since heat is caused due to resistance, also heat current triples.
