Description : Ohm’s law obeyed in - (1) a metallic conductor (2) a semi conductor (3) an electron tube (4) in all of the above
Last Answer : (1) a metallic conductor Explanation: There are, however, components of electrical circuits which do not obey Ohm's law; that is, their relationship between current and voltage (their I–V curve) is nonlinear (or non-ohmic).
