Question

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

Answer 1

resistivity directly proportion to voltage nd inversely proportional to current

Answer 2

Resistivity proportional to voltagev

And


Inversely proportional to current
