Answer:
C. magnitude of current
Explanation:
As per the question,
According to the heating effect of current flowing through a fixed resistor is mainly depends upon three-factor:
(1) The resistance of the wire.
(2) The magnitude of current flowing through resistor.
(3) Time interval
As per the Joule's law of electrical heating,
H = I²Rt
As we can see that the heat produced by passing an electric current through a fixed resistor is proportional to the square of the magnitude of the current.
Hence, the correct option is (C).
