Option 1: The SI unit of charge is ampere-second. This statement is correct. The ampere-second (A s) is the unit of electric charge in the International System of Units (SI).

Option 2: Debye is the unit of dipole moment. This statement is correct. The debye (D) is the unit of electric dipole moment. It is equal to 3.336 × 10^-30 coulomb-meter.

Option 3: Resistivity of a wire of length L and area of cross-section A depends upon both L and A. This statement is incorrect. The resistivity of a wire depends only on the material of the wire and its temperature, not on the length or area of cross-section. The resistivity (ρ) is a property of the material.

Option 4: The kinetic energy of an electron of mass m kg and charge e coulomb, when accelerated through a potential difference of V volt, is eV joule. This statement is correct. The kinetic energy (K.E.) of an electron can be calculated using the formula K.E. = eV, where e is the charge of the electron and V is the potential difference.

In summary, option 3 is not correct because resist
