Question

b) write ony three difference between resistance
and
specific resistance​

Answer 1

Answer:

Resistance

• Resistance is the property of material to oppose the flow of electric current passing through it.
• Resistance SI unit is Ωm.
• Resistance of conductor depends on its length, temperature, cross section area, material of the conductor.

Specific resistance

• Specific resistance is defined as the resistance offered by a unit length and unit cross-section of the substance to a current when a voltage is applied to it.
• Its SI unit is Ω−m.
• The specific resistance of a wire depends on the temperature and on the material that is used in the wire.

Answer 2

Answer:

Resistance

1)The ratio of the potential difference between the two ends of the conductor to the current flowing through at uniform temperature is called resistance of the conductor

2) the unit of resistance is ohm

3) Resistance of the conductor depends on its length, temperature, cross section area, material of the conductor.

Specific resistance

1) Specific resistance is defined as the resistance offered by a unit length and unit cross-section of the substance to a current when a voltage is applied to it.

2) The unit of specific resistance is ohm-meter (Ω-m).

3) Specific resistivity of conductor depends on the material of the conductor and its temperature
