In the figure given below, the polezero plot corresponds to _____________
In pole zero plot the two transmission zeroes are located on the jωaxis, at the complex conjugate location, and then the magnitude response exhibits a zero transmission at ω – ω_{C}.
A moving coil of a meter has 250 turns and a length and depth of 40 mm and 30 mm respectively. It is positioned in a uniform radial flux density of 450 mT. The coil carries a current of 160 mA. The torque on the coil is?
Given, N = 250, L = 40 x 10^{3}, d = 30 x 10^{3}m, I = 160 x 10^{3}A, B = 450 x 10^{3} T
Torque = 250 x 450 x 10^{3} x 40 x 10^{3} × 30 x 10^{3} x 160 x 10^{3}
= 200 x 10^{6} Nm = 0.0216 Nm.
In the circuit given below, the 60 V source absorbs power. Then the value of the current source is ____________
Given that, 60 V source is absorbing power, it means that current flow from positive to negative terminal in 60 V source.
Applying KVL, we get, I + I_{1} = 12 A …… (1)
Current source must have the value of less than 12 A to satisfy equation (1).
For a 2 port network, the transmission parameters are given as 10, 9, 11 and 10 corresponds to A, B, C and D. The correct statement among the following is?
Here, A = 10, B = 9, C = 11, D = 10
∴ A = D
∴ Condition for symmetry is satisfied.
Also, AD – BC = (10) (10) – (9) (11)
= 100 – 99 = 1
Therefore the condition of reciprocity is satisfied.
The condition for a 2port network to be reciprocal is ______________
If the network is reciprocal, then the ratio of the response transform to the excitation transform would not vary after interchanging the position of the excitation.
How many incandescent lamps connected in series would consume the same total power as a single 100 W/220 V incandescent lamp. The rating of each lamp is 200 W/220 V?
In series power = 1/p

In the given graph, there are 4 nodes and 6 branches.
Twig = n – 1 = 4 – 1 = 3
Link = b – n + 1 = 6 – 4 + 1 = 3.

The equivalent capacitance by applying the concept of seriesparallel combination of the capacitance is,
123 c Energy delivered during talk time
E = ∫V(t)I(t) dt
Given, I (t) = 2 A = constant = 2 ∫ V(t)dt
= 2 x Shaded area
The relation AD – BC = 1, (where A, B, C and D are the elements of a transmission matrix of a network) is valid for ___________
AD – BC = 1, is the condition for reciprocity for ABCD parameters, which shows that the relation is valid for reciprocal network. The ABCD parameters are obtained for the network which consists of resistance, capacitance and inductance, which indicates that it is a passive network.
Two networks are connected in series parallel connection. Then, the forward shortcircuit current gain of the network is ____________
The forward short circuit current gain is given by,
So, when the two networks are connected in series parallel combination,
So, h_{21} of total network will be sum of h parameter matrices.

We know that when a Wheatstone bridge is balanced, no current will flow through the middle resistance.
In the circuit given below, the value of R is ___________
The resultant R when viewed from voltage source = 100/8 = 12.5
∴ R = 12.5 – 10  10 = 12.5 – 5 = 7.55 Ω.
