Final answer:
The electrical resistance of a body is affected by its length, material composition, and temperature.
Explanation:
The electrical resistance of a body is affected by:
- Length of the body - directly proportional to resistance.
- Material composing the body - different materials have different resistivities.
- Temperature of the body - resistance increases with temperature.
These factors influence the resistance of a body, impacting its ability to conduct electrical current.
