Electric Network: The electrical components(resister,capacitor,inductor and supply sources) is connected in circuit in whatever i.e. series or parallel is called electrical network.

Complex Network:  It is those circuits which consists of many parameters (resister,capacitor etc) and these parameters are connected in such a manner that don’t solve easily by ohm law. When use ohm’s law for the solution of circuit so it’s required a lot of equation so we solve these circuits by different theorems. These circuits may be AC or DC.

Circuit: Circuit is a close conducting which allows current to pass or intending to pass pitch the circuit.

Open Circuit: Such circuits which not complete the path and its external resistance in infinite and zero current.

Short Circuit: Such circuit which provide shortest path to complete the circuit (before the load).  It’s resistance is zero and current is infinite.

Parameters  or Constant: The different element from which an electric  circuit are making is parameters or constant. i.e. resistance, inductance and capacitance.

Linear Circuit: Such circuit whose parameters do not change and remain constant with voltage or current is called linear circuit.

Non Linear Circuit: Such circuit whose parameters are change with voltage or current and do not remain constant is called non-linear circuit.

Unilateral Circuit: This is those circuit to which we apply the supply from only one side or they pass current from one side and from the other side they just behave like open circuit. i.e. diode, which is normally  used for rectification(conversion from AC to DC) process.

Bilateral Circuit: This is that type of circuit which pass the current from both side, OR they work in proper way when current is applied to it. i.e. transmission line etc.

Node: Appoint in a circuit which connect two or more than two circuit elements together is called node. OR Node is a point in a circuit from which current is distributed in two or more than two paths.

Branch: The path b/w two junctions is called branch.

A close path in a circuit which do not encounter any component more than one time.

Mesh: It is a component, which do not have any loop in it. OR Mesh is a loop, which has no loop within it.

IMEI : International Mobile Station Equipment Identity (IMEI)

There are following parts of an IMEI:

       -           Type Approval Code (TAC): 6 decimal places, centrally assigned.

       -           Final Assembly Code (FAC): 6 decimal places, assigned by the manufacturer.

       -           Serial Number (SNR): 6 decimal places, assigned by the manufacturer.

       -           Spare (SP): 1 decimal place.

                         Thus, IMEI = TAC + FAC + SNR + SP

International Mobile Subscriber Identity ( IMSI):

Mobile Subscriber ISDN Number ( MSISDN)

Mobile Station Roaming Number ( MSRN):

Time division multiple access :(TDMA)

FDMA:Frequency-division multiple access

A private automatic branch exchange :PABX

 
Quadrature Phase Shift Keying :(QPSK)

EEE General Knowledge- What is electricity

Electrical And Electronics Short Questions Answers

What is electricity:

All are made of atoms. In central atom is the nucleus may protons and neutrons. Tiny atom also has electrons spin around the nucleus. Electrons have a negative charge,and have positively charged protons.Electrons do not stay in one place. They move around different atoms so that some atoms has more protons, some have more Electrons. Sealed with more protons is positively charged. With more electrons Is negatively charged. When electrons move from one atom to another, it creates electric current.

EEE General Knowledge -Who discovered electricity

Electrical And Electronics Basic Questions Answers

Who discovered electricity:

The ancient Greeks knew that electricity can  be produced by rubbing two pieces felt together. But the first use of the word Power was by Sir Thomas Browne in which 1646 Book Pseudodoxia Epidemica (vulgar Errors). In 1752, Benjamin Franklin proved Lightning created by electrical charges.He tied an iron key kite string during Storm and showed that lightning struck Key. For this reason, he said Franklin has Discovered electricity. Today, we know that Lightning is the most common form of saw Natural Power. It is caused by clouds Encountering bears a negative charge to Positively charged objects on earth.
