- Conductors: Allows electric current to pass through it
- Insulators: Do not allow electric current to pass through it
- Most of liquids that conduct electricity are acids, bases or salts.
- Following are some good and bad / poor conductors of electricity
Liquid Good Conductor / Poor Conductor Lemon Juice Good Conductor Vinegar Good Conductor Tap Water Good Conductor Distilled Water Poor Conductor Vegetable Oil Poor Conductor Milk Good Conductor Honey Poor Conductor Soda Compounds Good Conductors Pure Fuels (Petrol, Diesel, Kerosene) Poor Conductors Sugar Solution Poor Conductor Spirit Poor Conductor - Chemical effect of electric current: When electricity is passed through the chemical the noticeable change takes place at the electrodes. These changes also helps in identification of positive and negative terminals of battery.
- Electroplating: A process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.

- Used method in industries for making metallic coatings.
- Gold and silver is coated on less expensive metal to make jewellery.
- Tin can used for storing food is made of iron and tin is coated above it.
- Zinc is coated on iron materials used for construction purposes
