Question

identical wire of aichrome and aluminium wire are connected in series unit of a battery a)which wire get heated more when swiched on?why? b) which ate the facters affecting the heay developed in a current carrying confuvtor? c) staye the law connecting them express it mathe matically​

Answer 1

Explanation:

a).Nichrome wire will get more heated. Explanation: This is because resistivity of nichrome wire is more than copper wire and also nichrome is a good conductor of current and has less resistance as compared to copper wire.

b).When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat.

c) .Ohm's Law Equation : V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
