What are the units of potential (V) in terms of Kg, Joules, and K (Kelvin)?

Thank you!

Electric potential (volts) is defined as watts dissipated per amp of current. Watts are units of power (Joules/second), so the units for volts is Joules per second per ampere. Note that temperature (kelvin) has nothing to do with it. If you want it in more fundamental SI terms you can replace Joules with N-m, or Kg-m^2/s^2, and replace Amps with Coulombs/s to get units of Kg-m^2/(C-s^2).
