Effects of electric current

Thermal Effect

The effect produced when electric current flows through a wire, causing the wire to heat up.

Chemical Effect

A reaction that occurs when electric current is passed through certain liquids, resulting in electrolysis.

Magnetic Effect

The phenomenon where an electric current flowing through a wire produces a magnetic field around it.

Electrolysis

The process by which electric current is used to cause a chemical reaction, often in liquids.

Electroplating

A method of coating a cheaper metal with a more expensive one using electrolysis.

Heating effect of electricity

Utilized in electric fires and heaters, where electical energy is converted into thermal energy.

Direction of Magnetic Field

The direction of the magnetic field is perpendicular to the flow of electric current and can be reversed by changing the current direction.

Electrolyte

A solution used in electroplating, which contains the coating metal, such as metal nitrate or sulphate.

Examples of Electroplating

Electroplating with silver (using silver nitrate electrolyte) and electroplating with copper (using copper sulphate electrolyte).
