Question

State Ohm's law. Draw a labelled circuit diagram to verify this law in tha laboratory. If you draw a flowing through a metallic conductor, what kind of curve will you get? Explain how would you use this graph to determine the resistance of the conductor.

Answer 1

ohm's law states that the potential difference is directly proportional to the current flowing through a conductor provided it's temperature is constant .the resistance is directly proportional to the area of cross section so we will be getting a parabola

Answer 2

ohms law formulae

V=I×R

Where v is voltage, I is current and R is resistance
