Question

The amount of heat produced in a wire depends on
(a) material
(b) length
(c) thickness
(d) all of these ​

Answer 1

Answer:

Option D is correct l.

Explanation:

It obviously depends on material. Because some are good and some are bad conductors of heat.

And

Amount of heat produced in wire = I²R

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 and material too.

Answer 2

Answer:

d

Explanation:

all of this can produce heat in a wire
