How was Ohm's Law proven wrong in 1909?

Ohm's law states that Voltage is directly proportional to the Current passing through the conductor.  It increases in case of conductors and decreases in case of semi-conductors. Hence Resistivity turned out to be a variable making the Resistance a variable too and hence proving Ohm's Law wrong.

Explanation:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
