SteveThe factors that affect the resistance of a conductor are the length of the conductor (longer length means higher resistance), the cross-sectional area of the conductor (smaller area means higher resistance), the material of the conductor (higher resistivity material means higher resistance), and the temperature of the conductor (higher temperature means higher resistance).

The property of a conductor that impedes the flow of charge is called?
The property of a conductor that impedes the flow of charge is called resistance. It is measured in ohms and depends on factors like the material, dimensions, and temperature of the conductor.
What do you mean by heating effect of current?
Current flowing through any conductor encounters resistance in that conductor. This resistance produces heat. (Think of tires on a car after driving on the highway. Smooth trip, but a small amount of friction (resistance) is inevitable.
What is encountered by the electric current while flowing through a conductor?
The electric current encounters resistance while flowing through a conductor, which results in the conversion of electrical energy into heat. This resistance is impacted by factors like the material of the conductor and its dimensions.
What effect will the cross-sectional area of the conductor have on the resistance of a conductor?
The cross-sectional area of a conductor is inversely proportional to the resistance of the conductor. Increasing the cross-sectional area decreases the resistance, as it allows more space for electrons to flow through, reducing collisions and increasing conductivity. Alternatively, decreasing the cross-sectional area increases resistance, as there is less area for electrons to flow through, leading to more collisions and increased resistance.
What happens to the resistance of a conductor when the length of the conductor is reduced to half?
If the length of the conductor is halved, the resistance of the conductor also decreases by half. This is because resistance is directly proportional to the length of the conductor. Shortening the length leads to fewer collisions between electrons and reduces the overall resistance.
