Define resistance and write factors affecting the resistance of a conductor
Answers
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistanceis measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
There are four factors that influence the resistance in a conductor. Thickness (cross sectional area of the wire), length, and temperature. The fourth factor is the conductivity of the material that is used. Some metals (copper, silver) are just more electrically conductive than others (iron, aluminum).
Answer:
the electrical resistance of an object is a measure of its opposition to the flow of electric current.
The resistance of the conductor depends on the following factors:
The temperature of the conductor.
The cross-sectional area of the conductor.
Length of the conductor.
Nature of the material of the conductor.
