State the relation correlating the electric current flowing in a conductor and the voltage applied across it.Also draw a graph to show this relationship

The relationship between the electric current flowing in a conductor and the voltage applied across it is given by Ohm's Law. Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Mathematically, it is represented as:

I = V/R

Where: I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms (Ω).

The graph showing this relationship is a straight line. The y-axis represents the current (I) and the x-axis represents the voltage (V). The slope of the line is equal to 1/R. This means that as the voltage increases, the current also increases linearly, assuming the resistance remains constant.

Please note that this law is a simplification and holds true only for certain materials (like metals) under constant conditions of temperature and pressure.
