Detailed Solution for Test: Series-Parallel Interconnection of Two Port Network - Question 7

At t = ∞ the circuit has effectively two 6Ω resistances in parallel Given voltage = 6 V
So, current = 2 A.

Test: Series-Parallel Interconnection of Two Port Network - Question 8

For the circuit given below, the value of z11 parameter is ____________

Detailed Solution for Test: Series-Parallel Interconnection of Two Port Network - Question 8   ∴ [z] = [1.775 + j4.26; -1.775 – j4.26; -1.775 – j4.26; 1.775 – j5.739] Ω.

Test: Series-Parallel Interconnection of Two Port Network - Question 9

Given two voltages, 50 ∠0 V and 75 ∠- 60° V. The sum of these voltages is ___________

Detailed Solution for Test: Series-Parallel Interconnection of Two Port Network - Question 9

The voltages can be written in the form,
50 + j 0.75∠-60°
= 37.5 – j 64.95
So, sum = (50 + 37.5) – j 64.95
= 87.5 – j 64.95 = 109∠-36.6°.

Test: Series-Parallel Interconnection of Two Port Network - Question 10

Consider a circuit having resistances 16 Ω and 30 Ωis excited by a voltage V. A variable resistance R is connected across the 16 Ω resistance. The power dissipated in 30 Ω resistance will be maximum when value of R is __________

Detailed Solution for Test: Series-Parallel Interconnection of Two Port Network - Question 10

We know that,
When R = 0, circuit current = V/30A
And Power dissipated = V2/30 Watts.
This is the maximum possible value which occurs for R = 0 Ω.

Test: Series-Parallel Interconnection of Two Port Network - Question 11

A 50 Hz current has an amplitude of 25 A. The rate of change of current at t = 0.005 after i = 0 and is increasing is ____________
