Tutor description

Resistor is a component used to control the size of the current that flows in an electronic or electric circuit. The size of the current that flows through a conductor depends on its resistance. The greater the resistance, the smaller is the current.Resistance: It is the property of a conductor due to which it poses an obstruction to the flow of current through it.

The size of the current that flows through a conductor depends on its resistance. The greater the resistance, the smaller is the current.Resistance:It is the property of a conductor due to which it poses an obstruction to the flow of current through it.Definition:Resistance of a conductor is defined as the ratio of potential difference (v) across the ends of the conductor to the current flowing through it. i.e. R = V/IWhere, 1ohm = 1 volt = 1V1 ampere 1AThus, one ohm is the resistance of the conductor through which a current of 1 ampere flows when a potential difference of 1 volt is applied across the ends of the conductor.SI UNIT : Ohm (W).DIMSENSIONS: [M1 L T-3 A 2 ].Cause of resistance of a conductor:Resistance of a given conducting wire is due to the collisions of free electrons with the ions or atoms of the conductor while drifting towards the positive end of the conductorR = r L ___(1)Thus from equation (1) we get that resistance of a material is1.
