Two identical wires one of nichrome and other of copper are connected in series and a current (I) is passed through them. State the change observed in the temperatures of the two wires. Justify your answer. State the law which explains the above observation.
Answers
Answer:
The temperature of nichrome wire will become very high because it is an alloy and has high resistivity. This can be explained by joules law of heating which states that the heat produced in a resistor is directly proportional to the Square of the current flowing through it, directly proportional to the resistance of the resistor and directly proportional to the time for which the current flows through the resistor.
