Question 1
The distributed capacitance Cd of a coil is being measured using a Q-meter. At a frequency of 1 MHz, resonance is observed with a capacitance of 150 pF. When the frequency is increased to 2 MHz, a different capacitance value is required for resonance, which is 30 pF. What is the value of the distributed capacitance Cd of the coil?
Question 2
The internal resistance of ammeters and voltmeter are 1 Ω and 1 KΩ respectively. If these meters are used to measure DC power. Find the value of load resistance at which error in V-A and A-V method is same.
Question 3
A PMMC type voltmeter, having a full-scale reading of 250 V and an internal resistance of 450 kΩ, is connected with the series resistance of 50 kΩ. Calculate the sensitivity of the voltmeter (in ohms/volts).
Question 4
What is the reading of 0.1234 volts on 10 V, 100 V range in 
digit DVM?
digit DVM?
Question 5
To minimize current deviation and voltage deviation in C.T. and P.T. respectively.
Question 6
For the given Lissajous figure if the horizontal frequency is 100 Hz, then the vertical frequency will be
