Why semi conductors are preferrd over conductors?

Answer 1

Conductors transport electrical energy easily. You can transfer the energy at the electrical pole to you light bulb without much loss from friction through a conductor like copper. Some semi-conductors are very interesting because they can be made to vary the flow of electricity through them. A small electrical signal can control the resistance of electricity through the semi-conductor. Thus a small signal can be made into a large signal, this is called amplification.

Answer 2

Semiconductors are preferred over conductors in electronic devices because they can be easily controlled to modulate the flow of electric current, allowing for the creation of transistors and diodes. They also have lower resistance compared to conductors, resulting in less heat generation and energy loss in circuits. Additionally, semiconductors are more compact and lightweight, making them ideal for modern electronics.
