Question
Explain the Structure of a Voltaic cell.
✓
Answer
A Voltaic cell is a plastic/glass container that contains two metal plates of two different materials and a liquid called an electrolyte. The metal plates are called electrodes. One of the plates acts as a positive terminal and the other as a negative terminal, and zinc is the negative terminal in a combination of copper and zinc plates, and zinc is the negative terminal in a combination of copper and zinc plates.
The liquid is put in a glass or plastic container, and the metal plates are partly dipped in the electrolyte. The electrolyte is usually a weak acid or a salt solution. A chemical reaction between the plates and the electrolyte produces electricity. When the circuit is connected, the electric current starts flowing from the positive terminal through the circuit to the negative terminal. Over time, the chemicals get used up, and the cell stops working. It is called a “Dead” cell that cannot supply any more electricity.
