Question

Define resistance (class 10) ​

Answer 1

Answer:

Resistance is a measure of the opposition to current flow in an electrical circuit.

Resistance is a property of conductor due to which it resists the flow of electric current through it. Component that is used to resist the flow of electric current in a circuit is called resistor.

Answer 2

Answer:

Explanation:

Resistivity is defined as the electrical resistance of a conductor of unit cross-sectional area and unit length. The resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to the area of cross-section of the conductor. SI unit of resistivity is ohm-meters.
