- The heating effect of electric current states that heat is produced when current flows through a resistance. - The amount of heat produced is proportional to the square of the current (I²), the resistance (R), and the time (t). - Fuse wire melts when the heat generated by excessive current raises its temperature to its melting point. - The specific melting current is determined by the material, length, and thickness of the fuse wire.
Working of safety fuses depends upon magnetic effect of the current chemical effect of the current magnitude of the current heating effect of the current Select the correct answer using the code given below.
