A transformer is an electrical device that transfers energy between circuits, while a thyristor is a semiconductor used for switching.

• Transformer Function: It changes the voltage level in AC circuits, allowing for efficient power transmission over long distances.

• Example of Transformer: Step-up transformers increase voltage for transmission, while step-down transformers reduce voltage for safe usage.

• Thyristor Funct...read more

Injection moulding and rotomoulding are two types of moulding processes used in manufacturing.

• Injection moulding involves injecting molten material into a mould cavity under high pressure, commonly used for producing small to medium-sized plastic parts.

• Rotomoulding, or rotational moulding, involves rotating a hollow mould filled with material in an oven until the material coats the inside of the mould, commonly us...read more
