What does the O and I mean on a switch

It is the IEC 5009 symbol and one of the many power buttons. That represent sleep mode or low battery state. It is also known as "the stand by button".until 2004, when it was replaced by a crescent moon. It is most confusing due to the binary numbers representation 0 and 1.

The common mean of 0 and 1 is either switch is ON or OFF.

In some cases, the button actually causes the micro to get the powered up when pressed. Which turns then some transistors to keep the power on. When we press the button to turn the device OFF, the micro-processor shut down everything including itself.

SAR Value

Hello Friends, Today I am going to tell you a important topic that is what is SAR Value. The acronym SAR(Specific Absorption Rate) is an mobile radiation range system or can say it is an measure of the maximum energy absorbed by a unit of mass of exposed tissues of a person using a mobile phone. SAR value is measured in units of watt per kilogram(1.6 W/Kg).

Prevention:-

To prevent from it check your mobile SAR Value by dialing *#07#. If your mobile SAR Value below 1.6 W/Kg then don't worry . You don't need to change your smartphone. If above from it then immediately change because it is too much dangerous for yourself.

Difference Between Li-Polymer and Lithium-ion battery

Lithium-Ion Battery:-

#.It loses actual charging capacity over time

#.High energy density

#. it has capacity to convert the battery into actual power upto 90%

#. It is more volatile as compared to polymer battery

#.It is more cheaper than polymer battery

#. It is heavy in weight as compared to polymer

#.Charging duration is long

Lithium Polymer Battery:-

                                                    #.It retains more charging than other 

                                                    #.It's energy density is low as compared to lithium ion

                                       #.It has low capacity to convert battery into actual power upto 80%

                                                   #.More safely there is less chance of explosion

                                          #.It is more expansive than lithium ion battery

                                                  #.It is light weight than others

                                                    #.comparatively charged within minimum time

और कुछ trading  apps हैं जिनके जरिये आप stocks/shares खरीद या बेच कर पैसा कमा सकते हैं
