Question

The resistance of a conductor is NOT dependent on?

• A. area of cross section of the conductor
• B. current flowing through the conductor
• C. temperature of the conductor
• D. length of the conductor

Answer 1

Answer:

B. current flowing through the conductor

• The resistance of a conductor depends on material properties, length, area of cross-section, and temperature but not on the current passing through it.

• The property of a conductor that opposes the flow of electric current through them and independent of the shape and size (length and area) of the materials but depends on the nature and temperature of the materials is called resistivity.

• It is denoted by R. It is denoted by ρ.

• The SI unit is the ohm(Ω).
