The heat produced in a current carrying conductor is directly proportional to the value of its resistance. From this information, one can say that the coil of an electric heater must have

(A) high resistance (B) low resistance

(C) Any moderate value of resistance (D) cant s

Open in App

Solution

As heat produced in a conductor is given by H= I²Rt where I is the current flowing through the conductor and R is its resistance.
As heat is not specified in the question, so we can not infer about the resistance of the coil.
