For teaching or experimenting the basic concept of generating electricity electrochemically. Voltaic cell consists of a chemically inert plastic jar with plastic cap fitted with ZINC and COPPER plates and external terminals. 4″ Diameter x 6″ Height. Includes general instructions. Multiple cells may be used to demonstrate connections in parallel or in series to gain higher current or higher voltage. Voltaic cell is also known as Galvanic cell, Voltaic Pile and Electric Cell.
