Every battery (or cell) has a cathode, or positive plate, and an anode, or negative plate.These electrodes must be separated by and are often immersed in an electrolyte that permits the passage of ions between the …
An electric current is provided by a 9 volt (V) battery. When electric current is supplied to the anode (penny) via the positive terminal of the battery, copper atoms are oxidized to form cations with a positive charge (Cu2+). The cations are set free in the electrolyte solution and are attracted to the cathode (dime), which is connected to the
