Conductor:  Through which current can flow easily i.e. with least resistance is called the conductor. The conductor is of three Types: A) Good Conductor B) Semi-Conductor C) Bad Conductor A) Good Conductor: Under normal room temperature, through which current can flow easily i.e. the number of free electrons is maximum, called Good Conductor. It gets hot quickly causing less durable. Example of Good Conductor: Platinum, Gold, Silver, Copper, Iron, Aluminium etc. B) Semi-Conductor: This material falls in between Good and Bad conductor. Not as good as Good Conductor and not as bad as Bad Conductor. The number of free electrons is minimal in this material. It’sRead More →
