NICE Circuit Analysis Question Paper
UNIT 1
1. What is a graph of a network ? :
When all the elements in a network is replaced by lines with circles or dots at both ends.
2. What is tree of a network? :
It is an interconnected open set of branches which include all the nodes of the given graph.

3. Properties of a tree in a graph :
** It consist of all the nodes of the graph
** If the graph has N no : of nodes the tree will have N-1 branches
** There will be no closed path in the tree
** There can be many possible different trees for a given graph depending on the no : of nodes and branches
4. Define Ohms Law :
The potential difference across any two ends of a conductor is directly proportional to the current flowing between the two ends provided the temperature of the conductor remains constant.
5. Define quality factor :
The quality factor is defined as the ratio of maximum energy stored to the energy dissipated in one period.
6. What are half power frequencies? :
In RLC circuits the frequencies at which the power is half the max /min power are called half power frequencies.
7. Define selectivity :
It is defined as the ratio of bandwidth and resonant frequency.
8. Write the characteristics of series resonance :
a) At resonance impedance is mim and equal to resistance therefore current is max.
b) Before resonant frequency the circuit behave as capacitive circuit and above resonant frequency the circuit will behave as inductive circuit.
c) At resonance the magnitude of voltage across inductance and capacitance will be Q times the supply voltage but they are in phase opposition.
9. What is anti resonance :
In RLC parallel circuit the current is min at resonance whereas in series resonance the current is max. therefore the parallel resonance is called anti resonance.
10. Define Ohms law :
The potential difference across any two ends of a conductor is directly proportional to the current flowing between the two ends provided the temperature of the conductor remains constant.
11. Write the characteristics of parallel resonance :
a) At resonance admittance is min and equal to conductance therefore the current is min.
b) Below resonant frequency the circuit behave as inductive circuit and above resonant frequency the circuit behave as capacitive circuit.
c) At resonance the magnitude of current through inductance and capacitance will be q times the current supplied by the source but they are in phase opposition.
12. Define KCL :
** KCL states that the algebraic sum of currents in a node is zero.
13. Define KVL :
** KVL states that the algebraic sum of voltages in a closed path is zero.
14. What is meant by linear and nonlinear elements? :
Linear elements shows linear characteristic of voltage Vs Current. Nonlinear element the Current passing through it does not change linearly with the linear change in applied voltage at a particular frequency
15. What is meant by active and Passive elements? :
If a circuit element has the capability of enhancing the energy level of a signal passing thorough it is called an active element. Passive elements do not have any intrinsic means of signal boosting.
UNIT 2
Network Theorems And Transformations
1 State superposition theorem. It states that the response of a linear circuit with multiple sources is given by algebraic sum of responses due to individual sources acting alone.
2 State Thevenin’s theorem. It states that any linear bilateral network can be replaced by a single voltage source, Vth , in series with a single impedance, Zth
3 State Norton’s theorem. It states that any linear bilateral network can be replaced by a single Current source, IN, in parallel with a single impedance, Zth
4 State max power transfer theorem. Max. Power is transferred to load impedance if the Load impedance is the complex conjugate of the source impedance.
5 State reciprocity theorem.
