Question

Draw v. I graph for an ohmic conductor​

Answer 1

GiveN :-

• To draw the V - I graph of Ohmic conductor .

SolutioN :-

We need to draw the V-I graph for an Ohmic conductor . As we know that According to Ohm's Law under same teemerature and other conditions , Potential difference applied across the end of the conductor is directly proportional to the current flowing through it . That is ,

$\sf \to \pink{ Voltage \propto Current }$

This implies when we increase the potential difference the current flowing also increases. The constant here is R which is the resistance . That is ,

$\sf \to \pink{ Voltage = ( Current )(Resistance) }$

This implies that Current is directly proportional to the Voltage . Hence the graph is a straight line passing through the origin O , as the graph shown below or may refer to attachment .

Also note that the ratio of V:I remains constant which is the resistance of the conductor . That is ,

$\sf\to \pink{ Resistance\gray{(R)} =\dfrac{Voltage\gray{(V)}}{Current\gray{(I)}}= Constant \gray{(C)} }$
