Question 1

In a circuit arrangement, lamps A, B and C having voltage of 6V are arranged across 12V supply voltage with current of 2.00A across the battery. which among the three lamps will have maximum brightness?

Question 2

In case of leakage flux circuit as shown, find the expression when resistance R2 is replaced by a resistor R on the primary side?

Question 3

In a transients LCR series circuit, which among the following shows underdamped condition?

Question 4

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): The coupling between two magnetically coupled coils is said to be ideal if the coefficient of coupling is unity.
Statement (II): Lower the self-inductance of a coil, more will be the e.m.f. induced.

Question 5

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): Photodiodes are not used in relay circuits.
Statement (II): The current needed to activate photodiodes is very low even at high light intensities.

Question 6

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:
Statement (I): Elements with non-minimum phase transfer functions introduce large phase lags with increasing frequency resulting in complex compensation problems.
Statement (II): Transportation lag commonly encountered in process control systems is a non-minimum phase element.

Question 7

When two resistors with resistances 6.0 Ω and 8.0 Ω are connected in series with 12 volts source, then the overall current in the circuit will be:

Question 8

What is the network equivalent resistance RTH across terminals A and B in the circuit?
circuitThevenin3

Question 9

If voltage across a lamp is 1.8V, then find the resistance of lamp, when current of 0.9A flows across it?

Question 10

For a given fixed tree of a network, the following form an independent set:
1) Branch currents
2) Link voltages
