Question

Draw an experimental setup to verify the ratio of V/I constant and also state the law its limitation and application is everyday life?​

Answer 1

Answer:

The experimental circuit diagram to verify the ohm's law is shown above.

In the circuit diagram, voltmeter V is connected in parallel to the conductor R and ammeter A is connected in series with conductor R. A power supply V

in

generates an electric current I in the circuit which is measured by ammeter A. As we changes the voltage of power supply, the potential difference across the conductor changes and we measure the corresponding current flowing through the circuit with the help of ammeter. Plotting a graph V Vs I gives a straight line which concludes that slope of the line i.e.

I

V

is a constant.
