If the resistance (R) of the conductor and time of flow of current in the conductor (t) remain unchanged, the relation between the heat produced (H) the conductor and flow of current (l) is
(a) H ∝ I
(b) H ∝ {1\over I^2}
(c) H ∝ I2
(d) H ∝ {1\over I}
(c) H ∝ I²
Explanation: According to Joule’s law of heating, the heat produced in a conductor is given by:
H = I2Rt
