00:05 The key topic is the chemical effects of electric current. 02:39 Indicator is used to determine if current is flowing in a circuit 07:25 Electricity flows through conductors and is blocked by insulators. 10:01 Insulators do not allow electricity to pass through them, while conductors allow it. 14:36 Current flows in a circuit when electrons move from one place to another, transmitting energy. 16:55 Current flows in a circuit and electrical appliances indicate its presence. 20:58 Electric current is the movement of electrical charge. 23:07 Current can flow in conductors but not in insulators. 27:18 Mixing a shot in water causes the shot to break down into its components, resulting in the formation of salt. 29:39 Electric current can flow in both solids and liquids if there is a charged carrier present. 33:58 The experiment demonstrates the chemical effects of electric current. 36:05 Chemical reaction occurs when electric current flows in a conducting liquid. 40:19 Chemical effects of electric current in the form of color change and deposition of metal. 42:30 The chemical effects of electric current involve metal deposition and formation of charge carriers. 47:02 Electroplating is the process of coating one material onto another material. 49:05 Electroplating is the process of depositing a layer of one metal on another metal using electricity. 53:17 Electroplating is the process of coating a material with a layer of another material using electricity. 55:15 Iron rusts due to the deficiency of iron, but electroplating can protect it from corrosion

24:12 As insulators don't have charged carriers so they resist the current flow and that's why they can't conduct electricity 56:15 In order to prevent rusting on iron, zinc is deposited. This process is called Galvanization.

[@Jivanshaw]

56:24 galvanization is the process of coating of zinc on the iron to protect it by rusting or we can also use paint to protect the iron

[@onions_]

Ok

[@hakkerffyt322]

Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.

The electricity flows in the sea water because when salt is dissolved in this water the components of salt are broken into pieces (Na+,Cl-). Na+ and cl- are cation and anion respectively. These are the forms of ions. As we know that ions are charge carriers so we can conclude that sea water is a good conductor as it consists of charge carriers which make the flow of electricity easy.

This is done to prevent rusting of iron by protecting it to come in contact with air and moisture. Zinc metal, being more reactive, reacts with air to form hard layer of zinc oxide, which prevents air from passing through it.( 56:36 )
