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 KΩ/volt. What will be the reading
in M
if the source voltage VO is a symmetrical square wave
of 800 volts
peak to peak ?

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
