## Sample EC8251 important questions:

What is electric circuit or electric network?

The combination of various electrical elements such as resistors, capacitors and inductors along with various energy sources such as voltage and current sources is called electric circuit or electric network.

Define branch and node.

Branch: It is a portion of a circuit with two terminal connected to it. A branch may contain one or more elements.

Node: It is a junction of two or more branches.

Define bilateral and unilateral network.

Bilateral network: The voltage-currant relationship is same for current flowing in either direction is called bilateral network.

Ex. R, L and C

Unilateral network: The network has different relationships between voltage and current for the two possible directions of current.

Ex: Diodes, vaccum tubes

Define static characteristics.
Static characteristics are the set of rules or criteria that is defined for those instruments that varies very slowly with time or remains a constant.

What is the property of additivity and homogeneity?

The principle of super position is a combination of additivity and homogeneity.

The property of addivity says that the response in a circuit due to number of sources is given by sum of response due to individual sources acting alone.

The property of homogeneity says that if al the sources are multiplied by a constant, then the response is also multiplied by the same constant.

What is meant by short and open circuits?

A short is conductor with zero resistance and an open is an infinitely large resistance. When we short circuit the resistance we replace the resistance by a conductor with zero resistance and when we open the circuit a resistance we remove the resistance.
