______________________________SOLUTIONS________________________________________

A circuit is a closed conducting path through which an electric current either flows or is intended flow.

• Linear circuit is one whose parameters are constant  i.e. they do not change with  voltage or current.

• Non-linear circuit whose parameters change with voltage or current

Q1.a

The various elements of  an electric circuit are called its parameters like resistance,inductance and capacitance . These parameters may be lumped or distributed. 

Q2.c

• Example of passive components : resistor,capacitor,inductor etc
• Example of active components : Diode,Trasistor ,voltage source,current source etc

Q3.b

Unilateral circuit whose properties or characteristics change with the direction of its operation.A diode rectifier is a unilateral circuit , because it cannot perform rectification in both directions.

Q4.a

Q5.d

Passive Network is one in which contains no source of emf in it.
