A conductor is an object or a textile that allows the menses of electrical electric current inward i or to a greater extent than direction. Metals similar Iron, Copper in addition to Aluminium are skillful conductors.
A insulator is a heart that does non allow the menses of electrical current. Diamond, mica, drinking glass in addition to forest are insulators.
Conductor vs Insulator
Conductor | Insulator |
Always allows the menses of electrical current. Substances that requires exclusively a minor potential divergence across them to drive a electrical current flow | Insulator does non allow the menses of electrical current. Current volition non menses fifty-fifty when potential difference is applied across them |
Good conductors has large publish of complimentary electrons | Insulators produce non comprise complimentary electrons or negligible complimentary electrons |
The electrical conductivity is based on the complimentary electrons due to metallic bonding | No electrical conductivity due to the absence of complimentary electrons |
The outer electron inward the atom tin live easily removed alongside a minor potential divergence applied | The outer electron inward the atom cannot live removed alongside potential divergence applied |
Conductor is a textile alongside depression resistivity | Very high resistivity |
Resistivity increases alongside increment inward temperature | Resistivity decreases alongside increment inward temperature |
They bring positive coefficient of resistance* | They bring negative coefficient of resistance |
In conductors, the conduction band is partially filled or it overlaps alongside the valence band | In insulators, the valence band is completely filled in addition to conduction band is empty |
The liberate energy gap is nix or real small | The liberate energy gap is real large |
The electrical electrical conductivity of a conductor decreases alongside increment inward temperature because the rising inward temperature increases the collision of electrons in addition to disturbs its complimentary flow. | Generally electrical conductivity increases alongside rising inward temperature every bit the electrons volition larn to the upper band. The availability of complimentary electrons inward the conduction band increases conductivity. |
They volition non acquit every bit an insulator at whatsoever temperature | Rise inward temperature Pb to rising inward publish of complimentary electrons thereby increases conductivity |
Mixing of impurities causes increment inward resistance in addition to decrease inward conductivity | No modify inward resistance in addition to conductivity |
Example of Conductor: Silver, Copper, Aluminium | Example of Insulator: wood, plastic, glass, diamond |
*The resistance-change element per score Celsius of temperature modify is called the temperature coefficient of resistance.
