Different types of water filters include reverse osmosis, activated carbon, UV filters, and ceramic filters.

• Reverse osmosis filters use a semipermeable membrane to remove contaminants.

• Activated carbon filters absorb impurities and improve taste.

• UV filters use ultraviolet light to kill bacteria and viruses.

• Ceramic filters physically block contaminants from passing through.

Various types of moulding processes used in manufacturing.

• Injection moulding - most common method for producing plastic parts

• Blow moulding - used for hollow objects like bottles

• Compression moulding - used for thermosetting plastics

• Extrusion moulding - used for creating long shapes like pipes

• Rotational moulding - used for large, hollow products like tanks

The current is the flow of electric charge in a circuit.

• Current is measured in amperes (A).

• It is caused by the movement of electrons or other charged particles.

• Current can be either direct current (DC) or alternating current (AC).

• DC flows in one direction, while AC periodically reverses its direction.

• Examples of current include the flow of electricity in a light bulb or the charging of a phone.
