Question

State Ohm’s law. Derive relation between I, V and R. Draw the graph between
V and I.

Answer 1

According to Ohm's Law, At Constant Temperature current flowing through a conductor is directly proportional to the potential difference across the wire.

V proportional to I           [only at Constant temp.]

V = IR [where R is constant of proportionality]

Graph of V and I is a straight line

Answer 2

hey mate !!!!


Ohm's law :-

according to Ohm's law

if the physical condition for example temperature remain unchanged the potential difference applied across the end of conductor is directly proportional to current flowing through it.




V directly proportional to I

means voltage directly proportional to current.




therefore, V = iR .
