Question

state ohm's law and draw the graph between potential(V) on the end of a conductor and current(I) flowing in cunductor

Answer 1

$\underline{\fbox{ { \sf \:◇ \: State \: Ohm's \: Law} }}$

☆ Ohm's Law states that electric current flowing in a conductor is directly proportional to potential difference across the ends of the conductor,provided temperature and other physical conditions remains constant.

$\underline{\fbox{ {◇ \: \sf \: draw \: the \: graph} }}$

$\boxed{ \sf V ∝R } \\ \boxed{ \sf \: V = Ri}$

This R is called electric resistance of the conductor , as you know it is the Opposite of the conductor for the flow of current through it, then so R being constant., so what we have

V ∝ i

Plot a graph by taking Potential on Y axis and current flowing around X Axis then it is straight line we can say passing through the origin with Slope R

let us draw a graph!!

★ Refer to the Attachment!!

$\tan \theta = \frac{V}{i}$
