Question

what happens when potential difference is applied across a conductor ​

Answer 1

Answer: This enables it to do work on charges wherever there is a potential difference e.g. in a filament. Potential difference (p.d.) is the energy transferred per unit charge between two points in a circuit . When the same p.d. is applied across different conductors, different currents flow.

What happens when potential difference is applied across a conductor ​

• The conductor will experience constant average velocity as the electrons move through it.

• The free electrons inside a conductor move only in one direction with a velocity of vd when a potential difference between the ends of the conductor is applied. This velocity is also known as drift velocity. There won't be any movement of the electrons in any other direction.
• One joule of work is required to convey a charge of one coulomb from one place to the other, resulting in a potential difference of one volt between two locations in a current-carrying conductor. Consequently, 1 joule divided by 1 volt gives us (1 coulomb) Using a device known as a voltmeter, the potential difference is measured.
• The electrons, which are negatively charged and oppose the direction of the electric field when it is applied across the semiconductor, move in the opposite direction of the electric field. The holes migrate in the direction of the electric field because they are positively charged.
• When an electric field is applied across a semiconductor, the negatively charged electrons reject the electric field's direction and travel in the other direction. Due to their positive charge, holes move in the direction of the electric field.
