Define following networks (i) Active (ii) Passive (iii) Unilateral (iv) Bilateral. 

2 Answers

Answer :

Ans: i) Active network: Active network is one which contains at least one source of e.m.f. or energy, is called active network. 

ii) Passive network: Passive network is one which does not contain any source of e.m.f. or energy in it, is called passive network. 

iii) Unilateral network: If the characteristic (response or behavior) of network dependents on the direction of flow of current through its elements, then the network is called as a unilateral network. 

iv) Bilateral Network: If the characteristic (response or behavior) of network is independent of the direction of current through its elements, then the network is called as a bilateral network. 

Answer :

An element capable of giving out power or energy to some external device is called an active element. e.g. battery, generator etc. An element which is not an active element and capable of absorbing or storing power or energy is called as passive element. 

Active Network: A network consisting of at least one active element (source of energy) is called active network. 

Passive Network: A network consisting of only passive elements i.e. no active element, is called passive network.
