Question 1

Consider the bridge shown in below figure and the data given during the balanced condition.

R1 = 81.9 Ω, r = 43.1 Ω,

R3 = 100 Ω, r = 200 Ω,

R4 = 200 Ω, C = 1 μF,

The value of R2 is _____?

and Value of L1 is ______?

Question 2

A CRO is working in xy mode. The input x(t) is a sinusoidal with amplitude 20 units, ω = 10 rad/sec. The input of x(t) is applied to differentiator and then attenuated by 10 times and then applied to y-terminals. The waveform observed on CRO will be

Question 3

A Digital voltmeter is accurate up to ±1% of reading plus 3 counts. When the voltmeter reads 1 V on 10 V range, the error in reading will be ____?

Question 4

A CT with a bar primary has 300 turns in the secondary winding. The resistance & reactance of the secondary circuit are 1 Ω and 2 Ω respectively with a 10 A following in the secondary winding, the magnetizing MMF is 100 AT and the iron loss is 1 watt. The percentage ratio error will be _____.

Question 5

A current transformer has a bas primary & 200 secondary turns ratio. The secondary winding burden is an ammeter of impedance (1.2+j0.5) Ω. The secondary winding has an impedance of (0.2+j0.3) Ω. The core required a current of 100 A for magnetizing & 50 A for core loss. How many turns could be reduced in the secondary winding in order that the ratio error be zero for this condition? The ammeter in the secondary winding circuit indicates 5 A.

Question 6

In the following circuit (HWR), the ammeter reads 13.46 Amp when it is of MI type. What would be the ammeter reading in A if it is of MC type?
