A cell emf 3V and internal resistance `0.75Omega` is connected to a nonlinear conductor whose V-I g raph is shown in figure obtain graphically the current drawn from the cell and its terminal voltage.

Explanation

Draw the straight line V=E-Ir where E=3 volt, r=`0.75Omega` on given figure the intersection of this line with V-1 plot for the conduc tor gives the required voltage 1.5V and current 2A.
