Question

What is a resistor and explain about resistivity

Answer 1

Resistor is a device which is used to obstruct the flow of electricity......

According to Ohm's low
Resistance is directly proportional to the current

Hope it'll Help You.......

Have a nice day....

Answer 2

The resistor is a passive electrical component to create resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals. The current is proportional to the voltage across the terminal ends.



resistivity
________


Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.

Although materials resist the flow of electrical current, some are better at conducting it than others.The resistivity is a figure that enables comparisons of the way in which different materials allow or resist current flow.
