reduction techniques.
(b) Explain
types of elements in detail.
(c)
Find the single equivalent resistance between a and b in the circuit shown
below by network reduction techniques.
Ans:22.5Ω
2. (a)
Write short notes on star – delta transformation. If Rab, Rbc and Rca are
connected in delta, derive the expressions for equivalent star connection
(b) Using star/delta and delta/star conversion, find the resistance
between the terminals A and B as shown in figure
Ans:1.33Ω
3.
(a) State and explain Superposition theorem.
(b) Using superposition theorem determine the
current through 12 Ω resistor
(All resistances are in Ω) as shown in
figure.
4. (a) State and explain Thevenin's
theorem. Explain significance of Thevenin’s theorem on network theory
(b) By using Thevenin’s theorem determine the current through 5 Ω resistor
(All resistances are in Ω) as shown in figure.
5. (a).State and explain Norton’s theorem
(b) Find the current through branch ‘be’ using Norton’s
theorem
Ans:0.227A
6. (a) State and explain
Maximum Power Transfer theorem.
(b) Calculate the value of
load resistor RL to be connected across terminals A and B which would draw the
maximum power from the circuit and also find the maximum power in the circuit
shown below.
