Question

the amount of heat depends upon wire a) material b) length c) thickness d) all of these
​

Answer 1

Answer:

Explanation:

Amount of heat produced in wire = I ²R

Where R = Resistance of wire

           I = Current through wire

As resistance of wire   R∝ L/A

 

So heat produced depends on Length as well as thickness.        

Answer 2

Answer:

(d). All of these
