(h)Symbolic representation of diode:

(ii) The direction of current flow is represented by the arrow head.

(iii)In equilibrium state current does not flow in the junction diode.

(iv)In can be presumed to be equivalent to a condenser in which the depletion layer acts as a dielectric.

(v)Potential distance curve at P-N Junction

(vi)Charge density curve at P-N Junction

(vii)Curve between electric field and distance near P-N junction
