inside the 555 timer, there are 3 resistors used in series to get vcc/3 and 2*vcc/3 ....
all the 3 resistors used are same and are 5k ohm resistors..
so its called 555 timer..
acknowledgement guys ... am kinda sure though, but plz verify it ...
as i thought 555 timer is called so because of the fact that it consist three 5Kohm resistor in series and with the help of these resistors there is a delay of time and also other fact which make it timer is that timing of the pulses can be controlled through this.It basically works as a clock timer.............................
I hope its the perfect answer..............
IC 555 is named as timer, it is one of the most useful ic
in electronic circuit. It consist of 3 resisters having the
capacity of 5kohm each, and with the help of these
resisters it can create a time delay, so it is called timer.
dekho baat zara aise hai ki 555timer mein hot to kachu nai
hai mano 3resistor se hot hain . aur be apne matlab ki
series mein jude rehat hain .aur 1 aur baat zara ja hai ki
be jo resistor hain kaho to unki aukat 5kohms ki hot hai
jaa ke mare bahein 555 timer kehat hain
kai answer keso lago dekho bhai lage kaiso bhi mano sahi hai
The 555 timer is an integrated circuit (chip) implementing
a variety of timer and multivibrator applications.The 555
gets its name from the three 5-KΩ resistors used in typical
