problem 1: Why are electronic instruments becoming more and more famous in spite of the fact that such instruments are costlier in comparison to the electrical instruments?
 
problem 2: Why are TVMs chosen over the VTVMs?

problem 3: How do we get the scale of average reading voltmeter by using vacuum tube diode uniform and independent of variations of tube plate resistance?

problem 4: Why is dc amplifier related with diode rectifier in the peak reading ac voltmeters given with stabilizing means?

problem 5: What do you mean by Q-factor of the coil and why a coil of high Q is chosen over the coil of low Q?

problem 6: What do you mean by Q-meter and on what principle does it work?

problem 7: How does the distributed capacitance influence the effective value of the Q of a coil?
 
problem 8: What is the basic difference between a CRT and CRO? Draw a block diagram of a general purpose CRO and describe the functions of each block.

problem 9: Draw a block diagram of a CRO and describe the function of each block.

problem 10: Draw and describe the construction of the CRT.
