A current I is passing flowing through a thin copper slab placed on a diamond slab. The bottom surface of the diamond slab is maintained at 0^ C and the remaining arrangment is thermally insulated from the surroundings. Note that diamond is an excellent thermal conductor but a poor electrical conductor. Then, the correct option(s) is(are)

Options

1. Athe steady-state temperature of the copper slab is directly proportional to the thickness of the diamond slab.
2. Bthe steady-state temperature of the copper slab depends upon the specific heat of the copper.
3. Cif the current is supplied from a constant voltage source, the steady-state temperature of the copper slab wil
4. Dif the current is held constant, the steady-state temperature of the copper slab will be halved if its thickne
