Question
Name the electrical property of a material whose symbol is "omega".
Solution
Resistance is represented by the symbol Omega, Ω. Resistance has the following electrical properties:
- The resistance of a conductor depends on its length. It is directly proportional to the length, R α L.
- The resistance of a conductor is inversely proportional to its area of cross-section, i.e. R α 1 / A.
- Resistance depends on the nature of the material of the conductor.
- Resistance also depends on the temperature of the conductor.
