FAQs on Factors Affecting the Resistance of a Conductor Video Lecture - Physics for Class 10
| 1. What is the definition of electrical resistance? |  |
Ans. Electrical resistance is the property of a conductor that hinders the flow of electric current through it. It is caused by collisions between the moving electrons and the atoms of the conductor.
| 2. What are the factors that affect the resistance of a conductor? | |
Ans. The factors that affect the resistance of a conductor are:
- Length: The longer the conductor, the higher the resistance.
- Cross-sectional area: The larger the cross-sectional area, the lower the resistance.
- Material: Different materials have different resistivities, which affect the resistance.
- Temperature: The resistance of most conductors increases with an increase in temperature.
- Presence of impurities: Impurities in the conductor can increase its resistance.
| 3. How does the length of a conductor affect its resistance? | |
Ans. The length of a conductor directly affects its resistance. Longer conductors have more atoms for the moving electrons to collide with, resulting in more resistance. Therefore, as the length of the conductor increases, its resistance also increases.
| 4. Why does the cross-sectional area of a conductor affect its resistance? | |
Ans. The cross-sectional area of a conductor inversely affects its resistance. A larger cross-sectional area provides more space for the electrons to flow, reducing the number of collisions between electrons and atoms. As a result, a conductor with a larger cross-sectional area will have lower resistance compared to a conductor with a smaller cross-sectional area.
| 5. How does temperature affect the resistance of a conductor? | |
Ans. In most conductors, an increase in temperature leads to an increase in resistance. This is because as the temperature rises, the atoms in the conductor vibrate more vigorously, causing more frequent collisions with the moving electrons. These collisions hinder the flow of electrons, resulting in higher resistance. However, some materials, like semiconductors, exhibit a decrease in resistance with increasing temperature.
