Answer» There are some major factor on which heat produced in current carrying conductor depends upon. Some of the major ones are: Resistance of the conductor: Heat produced in conductor is product of square of the current and resistance ie (P=I*I*R). So, higher the resistance of the conducting wire, more is the loss in it. Current in the conductor: Heat produced is proportional to square of the current flowing in the conductor as governed by the equation in (1). Amount of time current flows: Also, the heat produced is dependent upon the amount of time current flows in the conductor. actually answer Kya h actual ans batlana bhi |
