1. Material: Different materials have different resistivities, which affects the resistance of the conductor. For example, materials like copper and silver have low resistivities, making them good conductors, while materials like rubber have high resistivities, making them poor conductors.
2. Length: The longer the conductor, the higher the resistance. This is because electrons have to travel a longer distance through the conductor, experiencing more collisions with atoms along the way, which increases resistance.
3. Cross-sectional area: The larger the cross-sectional area of the conductor, the lower the resistance. This is because a larger area allows more electrons to flow through the conductor, reducing the chances of collisions and increasing conductivity.
