Basic Difference between Male & Female in Electronics Connectors

Basic distinction Between Male & female in electronics Connectors

Electronic cables typically have male connectors at every finish.All the electronic devices you utilize in your home electronics have connectors that are available male and female elements. This commonplace arrangement ensures that a connecter fits solely with the alternative gender of constant sort, serving to to standardize cables for power, analog and digital signals. The male differs from the female gender in this it's one or additional signal-carrying pins or protrusions; these work snugly in complementary receptacles on the female connecter.

Terminology and Identification
Technicians discuss with male electrical connectors as plugs, and to females as receptacles, jacks or sockets. In most cases, you'll simply tell a connector's gender: the male half has sticking metal conductors separated by a plastic dielectric. the female has one or additional sockets simply massive enough to simply accept the male pins. AN RCA male connecter, as an example includes a central pin enclosed by a metal shroud; the female includes a cylindrical metal hole that accepts the pin on the within and also the shroud on the skin. BNC connectors, used for radio-frequency instrumentation, ar tougher to tell apart between male and femalevariations, as each have jutting elements.
 
Orientation and Polarity
The elements in male and female connectors ar homeward specified the 2 work tightly along. additionally, several connectors have a pin layout that stops instrumentation from being connected backwards. A polarized wall plug, as an example, has 2 slots: one for warm and one for neutral power, however the neutral slot is wider. as a result of this distinction, you can't insert a two-pronged electrical device into the female backwards. alternative connectors, like those used for Apple's "Lightning," work along in 2 orientations, and each work properly.
Cable and Panel
Although not a strict rule, most cables have male connectors; females are mounted to instrumentation panels. femalesockets usually have a recessed style, permitting AN instrumentation cupboard to possess a comparatively sleek profile freed from protrusions. within the case of the plug, the female panel connecter has most of the hardware behind the front panel; solely a metal washer and a slim nut extend on the far side the panel's surface.
Design
Because male and female connectors work along, they're similar however ne'er identical. the dimensions of the male pin and female receptacle ar inside thousandths of an in. of every alternative, despite the layout. the female accepts the male usually with a coffee insertion force, creating connections straightforward. On some connectors, like the XLR connecter employed in skilled audio instrumentation, the female includes a latch that captures the male, preventing a user from actuation it out accidentally.






how it works computer power supply

Tuesday, 27 January 2015

We'll find out how laptop power provides work and what the power ratings mean.

In a notebook computer (PC), the facility provide is that the metal box typically found in a very corner of the case. the facility provide is visible from the rear of the many systems as a result of it contains the power-cord receptacle and also the cooling fan.

Power provides, typically remarked as "switching power supplies", use whipper technology to convert the AC input to lower DC voltages. the everyday voltages provided are:     3.3 volts, 5 volts,12 volts.









                                                       PC power supply

               
The 3.3- and 5-volts ar generally utilized by digital circuits, whereas the 12-volt is employed to run motors in disk drives and fans. the most specification of an influence provide is in watts. A watt is that the product of the voltage in volts and also the current in amperes or amps. If you've got been around PCs for several years, you almost certainly bear in mind that the initial PCs had massive red toggle switches that had a decent little bit of heft to them. after you turned the laptop on or off, you knew you were doing it. These switches truly controlled the flow of one hundred twenty V power to the facility provide.

­­Today you switch on the facility with a trifle electrical switch, and you switch off the machine with a menu possibility. These capabilities were other to straightforward power provides many years agone. The software system will send a sign to the facility provide to inform it to show off. The electrical switch sends a 5-volt signal to the facility provide to inform it once to show on. the facility provide additionally features a circuit that provides five volts, referred to as VSB for "standby voltage" even once it's formally "off", in order that the button can work. See future page to find out additional concerning whipper technology.

 Electrical and Electronics Dictionary

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
