Question

State ohm's law . Derive the relationship between I, V and R. Draw the graph between V and I

Answer 1

Answer:

THE ANSWER IS:-

Explanation:

In 1827, a german physicist Georg Simon Ohm found out the relationship between the current I, flowing i na metallic wire and potential difference across its terminals. The potential difference V across the ends of a given metallic wire in an electric circuit is directly proportional to the circuit flowing through it, provided its temperature remains the same.

This is known as Ohm's law.

where V~I

V/I =constant

V/I =R

here V is the p.d, I is the current, and R is the resistance.

Answer 2

Answer:

At constant temperature, the potential difference v across the end of a given metallic wire in an electric circuit is directly proportional to the current flowing through it.

V directly proportional I

OR

V=IR

no effect of Vand I on R because as V increase, I increase but R remains the same
