Question

A current of 2 A, passing through a conductor produces 80 J of heat in 10 seconds. The resistance of the conductor in ohm is (A) 0.5 (B) 2 (C) 4 (D) 20

Tardigrade Admin · Accepted Answer

H=I2Rt or R =(H/(I2 t))=(80/(22 × 10)) = 2 Ω

Q. A current of $2 A$ , passing through a conductor produces $80 J$ of heat in $10$ seconds. The resistance of the conductor in ohm is
