Answer
The correct answer is c) present magnitude.
The heat generated by an electric current travelling through a fixed resistor is proportional to the square of the current magnitude.
The heat produced by passing an electric current through a fixed resistor is proportional to the square of: a) magnitude of resistance of the resistor b) temperature of the resistor c) magnitude of current d) time for which current is passed
