1. The wave shape of Vo in the figure will be


2. In figure, the  ideal moving iron voltmeter M will read 


3. M in figure is a rectifier type 200 Volts full scale voltmeter

    having a sensitivity of 10 K/volt. What will be the reading

    in M if the source voltage VO is a symmetrical square wave 

   of 800 volts peak to peak ?

(a)             (b)          (c)           (d)


4. In figure, A1, A2 and A3 are ideal ammeters. If A1 reads

    5 Amps, A2 reads 12 Amps, then A3 should read________.


5. The built in potential (Diffusion Potential) in a PN junction 


6. Consider the circuit shown in figure (a). If the diode used here 

    has the V-I characteristic as in figure (b), then the output 

    waveform Vo is
