Question

How does the heat produced by a current passing through fixed resistance wire depend on the magnitude of current?

Answer 1

Explanation:

The heating effect of current through a fixed resistance is given by formula where I is the current, R is the fixed resistance and T is the time for which the current has been flowing.

The above three factors are responsible for the heat that is produced due to flow of current.

Resistance is the hindrance or reluctance that, a conductor or the material through which current is flowing, has to offer.

This hindrance or resistance in path of current produces heat as byproduct thus more the current more is the heat.
