Question

which of the following does not affect the electrical resistance of a body? a) bodies directly surrounding the body b) temperature of the body c) material

Explanation:

To determine which factor does not affect electrical resistance, we analyze each option:

• Option B: Temperature affects resistance (e.g., most metals' resistance increases with temperature).
• Option C (Material): Different materials have different resistivities, so material affects resistance.
• Option A: The bodies surrounding a conductor do not impact its internal electrical resistance, as resistance depends on the conductor's own properties (material, length, cross - sectional area, temperature) rather than external objects.

Answer:

A) Bodies directly surrounding the body
