Types of Network, Mesh, and Nodal analysis
Q1) For the characteristics given below comment about the type of element?
A1) It is a Linear, Bilateral and Passive element
Q2) For the figure below comment on the type of element?
A2) The element is Non-Linear, Passive, and Unilateral.
Q3) For the circuits given below write the voltage equations:
A3) Let current i1be in loop 1 current and i2 for loop 2
Q4) Write the loop equations for the given circuit below?
A4)
For loop 1
For loop 2
Q5) Using nodal analysis find the voltage across 5resistor.
A5)
For V1
1
For V2
2
Solving 1 and 2:
For 5 voltage =
= -50.9 + 57.27
= 6.37V
Q6) Find
A6)
= 2H + 3H +10H - 2(10H)+ 2(4H) + 2(6H)
= 15H + - 20H + 20H
= 0
Q7) Find
A7)
5H + 6H + 9H - 2(1H) -2(5H) -2(3H)
= 2H
Q8) Find dual for the series RLC circuit?
A8) Let us consider the RLC circuit
Fig RLC Circuit
Applying KVL we have
v(t) = ri(t) + L +
So, dual of the above network will be
Fig Dual of RLC circuit
i(t) = Gv(t) + C +
Q9) Define lumped and distributed elements?
A9) Lumped and Distributed: Lumped elements are Physical dimensions of the circuit are such that voltage across and current through conductors connecting elements does not vary. The current in the two-terminal lumped circuit element does not vary. In distributed elements, the current varies along conductors and elements. The voltage across points along the conductor or within element varies.
