1. Which of the following does not affect the electrical resistance of a body?

A. Length of the body
B. Material composing the body
C. Bodies directly surrounding the body
D. Temperature of the body



Answer :

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:

  1. Length of the body - directly proportional to resistance.
  2. Material composing the body - different materials have different resistivities.
  3. Temperature of the body - resistance increases with temperature.

These factors influence the resistance of a body, impacting its ability to conduct electrical current.
