electrochemical cells

why is my overall equation wrong, isn't reduction occurring at electrode A and oxidation at electrode B?IMG_BECB65017B1C-1.jpeg

The cell is being recharged so you have to flip the equation. The one you have written is discharge.Recharge is the opposite of discharge hence the flip

I had thought the normal equation is when the cell is being charged/recharged whereas when it's being discharged the equations will flip. Is there an explanation as to why the normal equation is when the cell is being discharged?

Because you have a positive EMF it must be discharge I think
