Here are some more examples of ‘the’ used with proper names. Try to say what these sentences mean. (You may consult a dictionary if you wish. Look at the entry for ‘the’) Mr Singh regularly invites the Amitabh Bachchans and the Shah Rukh Khans to his parties.

A voltage source V=V_(0) sin (100 t) is connected to a black box in which there can be either one element out of L,C,R or any two of them connected in series. At steady state, the variation of current in the circuit and the source voltage are plotted together with time.using an oscilloscope, as shown If AC source is removed, the circuit is shorted for some time so that capacitor is fully discharge and then a battery of constant EMF is connected across the black box, at t=0 .The current in the circuit will-

It is possible to take a high quality photograph of a very fast moving object by illuminating the object for quite a small fraction of a second. You may have come across photographs of a bullet penetrating a banana or an apple in many text books or magazines. This is called 'stop action' photography because the fast moving object travels a very short distance during the time of illumination. Harold Edgerton, the inventor of stroboscope, was a pioneer of this kind of photography. A normal photographic plate works properly if it receives an energy of 4J during the exposure. To release this energy in a very small fraction of time, huge amount of power is required. Such huge power can not be generated directly from a battery because of its high internal resistance. To produce such power a capacitor is used. The time in which a capacitor discharges can be very short. Although, theoretically it would take a long time for a capacitor to discharge completely, it discharges almost completely in about 10 time constant. Consider the following situation A capacitor of 200muF storing 4J energy is made to discharge through a flash light in 2ms. This setup is used to take the picture of a bullet moving at a speed of 100m//s Assume that the flash light acts as a resistor and there is no other resistance in the circuit. What is the order of energy delivered to the flash light in 0.2 ms(approx).
