Draw the graph showing the variation of current with voltage for a p-n junction diode.

Draw a graph showing the variation of stopping potential with frequency of incident raditions in relation to photoelectric effect. Deduce an expression for the slope of this graph using Einstein's photoelectric equation.

Draw the graph to show the variation of X_C with the frequency of the ac source used.

Draw a graph to show the variation of resistance of a metal wire as a function of its diameter, keeping length and temperature constant.

Photoelectric effect When light of sufficeintly small wavelength is incident on a metal cathode, it may emit electons called photoelectrons. Above threshold frequency the stopping potenital and hence the energy of the photoelectrons are directly proportional to the frequency. in the given figure, we see the variation of stopping potential with the frequency of incident radiation for three metals A, B and C. Slope of graph is given by

Plot a graph showing variation of induced emf with the rate of change of current flowing through a inductor coil.
