What is an electric cell? Explain with the help of a neat, labelled diagram.
Answers
Answer:
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions.
An electric cell is a device which produces electricity capable to run smaller appliances like torch, clock, camera, radio etc. An electric cell has two terminals – positive (+) and negative (-). Positive side of an electric cell has a metal cap.
- Galvanic Cell / Voltaic Cell
Chemical energy is transformed into electrical energy in these electrochemical cells.
- Electrolytic Cell
Electrical energy is transformed into chemical energy in these cells.
A simple cell consists of two solid electrodes placed in an electrolyte connected together by an electrical conductor such as wire. The two electrodes must be two different metals. The electrolyte can be acid solution, alkaline solution, salt solution or even a fruit such as orange or lemon.
The electric cell produces electricity from the chemicals stored inside it. When all the chemicals in the electric cell are used up, the electric cell stop producing electricity. Ordinary electric cells cannot be recharged.
Answer:
An electric cell is a device, which converts chemical energy into electrical energy. It has two terminals, which are made up of metal: one terminal is positive, while the other one is negative. When the two terminals are connected to an electrical device, electric current flows through it.
