Learn Class 8 Science - Chemical Effects of Electric Current

What are metals? And what are the electric effects of current? We all are aware that metal is a good conductor of electricity. At the same time, plastics are not the conductors of electricity. There are also many liquid conductors which become a source of electricity.

Electric current

• The path consists of passing or taking current.
• And the current flows in it even when the current’s path is closed.
• Where the break-in path leads to no formation of current.

Chemical effects of electric current

The chemical reactions can occur when the current gets passed through the chemical solutions. It consists of:

• Colour changes.
• Metal Deposition
• Gas bubbles form.

How to check current?

Many ways can help you to check current. These are:

1. Conductor:

• The term ‘conductor’ refers to the tool which allows it to pass the current.

2. Tester:

• A tester is a tool that helps to check the electric current.
• In the tester, there is a presence of a led bulb.
• The LED bulb will help you to determine the current.

Electrodes:

Two types:

• Cathode
• In the tester, there is a presence of a led bulb.
• Anode

Electroplating:

Electroplating is the process of the deposition of layers. And this layer gets on the other material with the help of electroplating.
