Resistance is the property of material to oppose the flow of electric current passing through it. 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.

Answer 2

¢ RESISTANCE IS THE OBSTRUCTION FACED BY MOVING ELECTRON ( CURRENT ) . DUE TO THE PRESENCE OF PARTICLE IN THE MATERIAL ( PROTON ) .IT IS THE PROPERTY OF THE SUBSTANCE , WHICH DEPENDS UPON SPECIFIC RESISTANCE OR RESISTIVITY , MATERIAL , LENGTH AND CROSS SECTIONAL AREA...

THE S.I UNIT OF RESISTANCE IS OHM....
