Question

State the Ohm's law and show slope for 20 ohm and 40m on I-V graph

Answer 1

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Answer 2

Answer:

limitations of ohms law: it is valid for metal conductors provided temperature and other physical conditions remain constant. the resistance of the material changes with temperature. it is not applicable for a gaseous conductor
