Question

Flow of electrons is affected by the which factor

Answer 1

Answer:

flow of electrons is affected by the change and resistance...

Answer 2

Answer:

The flow of electrons is affected by the resistance.

Explanation:

• The flow of electrons through a conductor is called electric Current.
• The conductor consists of positive ions surrounded by free electrons. The positive ions vibrating in fixed positions, obstruction the free flow of electrons.
• This obstruction is called resistance. The resistance is the property of the material that restricts the flow of electrons.
• The factors affecting resistance are length, cross-sectional area and nature of the material of conductor.
• Resistance is given by $R=\frac{\rho L}{A}$ where L is the length, A is the cross-sectional area and  ρ is the resistivity of the conductor.  
• Resistance also depends on temperature. If the temperature of a conductor increases, the ions vibrate more vigorously, thus obstructing the free electrons more.
• Hence, the resistance restricts the flow of electrons.
