Question

Present the relationship between the voltage applied across a conductor and the current flowing through it graphically.

Answer 1

Hint :We know the relationship between the voltage applied across a conductor and the current flowing through is always linearly proportional.
The formula between voltage and current is
 $ V=IR $

Complete Step By Step Answer:
The potential difference across a conductor is proportional to the current through the resistor.
 $ V\propto I $
 $ V=IR $
This is similar to the equation of a straight line passing through the origin.
So, the graph between voltage and current is a straight line with a slope of $ R. $

Note :
The relationship between current voltage and resistance is expressed by Ohm’s law. The states that the current flows in a circuit are directly. Proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains’ constant. Relation between voltage and current is linearly proportional.
