Draw graphs showing variation of photoelectric current with applied voltage for two incident radiations of equal frequency and different instensities. Mark the graph for the radiation of higher instensity.

Sketch graphs to show the variation of (i) current and (ii) impedance of a series LCR circuit with the frequency of the ac source.

Draw a graph to show the dependence of stopping potential on the frequency of incident light in case of photoelectric effect. Indicate the threshold frequency in the graph.

In case of photoelectric effect, the graph of kinetic energy of photoelectron with respect to the frequency of incident radiation will be a straight line. The slope of this straight line depends on

Draw a characteristics curve of zener diode showing the variation of volatage with respect to the currrent and indicate the position of "zener voltage" in the graph.

A cell of emf E and internal resistance r is connected across a variable resistor R. Plot a graph showing variation terminal voltage V of the of the cell Versus the current I. Using the plot,show how the emf of the cell and its internal resistance can be determined.

The same enzyme catalyzed reaction showed two different kinetic patterns as shown in the graph. Y-axis indicates product formed and X-axis indicates time. Mark the correct interpretation.

The insultated plates of a charged parallel capacitor (with small separation between the plates) are approaching each other due to electrostatic attraction. Assuming no other force to the operative and no radiation taking place, which of the following graphs approximately shows the variation with the (t) of the potential difference (V) between the plates?
