Re: Refrigerator Problem
Start the refrigerator when the other instruments are off , and the voltage stabilizer is out of service ; in this way you can find out if the voltage is low for it or not.
If it works normally , you could use the stabilizer in service now, and find if there is any...
As a general answer we should select BJT as the faster one... BUT when we say about the switching and digital ckt, CMOS is the winner, since its newer technology helps it to use narrower channels to get the winning speeds.
In analog ckt, when we don't use a BJT is saturation mode,and it is in...
Re: BJT is definitely faster than MOS....Please acknowledge.
As a rule, we should say BJT is faster than CMOS.... BUT it is not a complete rule, because nowadays there are some CMOS technologies that can rival with BJTs in speed !

As a matter of fact, the first advantage of CMOS ckt is its lower energy consumption, and the ability of usage with several levels of voltages... eg. we need 5 volt for BJT 74xxx ICs, but not necessarily for 74cxxx ones.
However, in some cases we may see a very fast modern CMOS IC which has...
Hi.
I should confirm fsahmed another time.
He has good information on capacitors, and he almost said anything about Cap.s and the effect of higher voltages on their sizes.
You may use ceramic or mylar capacitors for your higher voltage applications.
Re: resolution
Resolution is a describing adjective for some electronic instruments which are involved with data acquisition, sending, or receiving...
Then resolution shows the quality of the data.
For example, an HDTV has a very higher resolution than a conventional TV; because the pixels of...
Re: Transistor
Hi. How do you do?!
BS170 is a good replacing candidate,you only need to notice the pin-out !
I put the information in the attached file for you.
VQ1000j and VQ1000p are suitable replacements also, but they are in Dual-in-Line package.
You may use NDF7000A easily too. Its pin...
ac voltmeter measurement opamp
Hi !
I am happy hearing so good questions.
I confirm the previous aiding tip written by Mr/Ms. laktronics.
AND suggest you to use the voltage follower ckt instead.
It is a simple circuit built with an op-amp,that follows right voltage to the output without putting...
Re: 555 CIRCUIT
I suggest putting a 56ohm resistor at collector, and changing the base resistor to 7.4k-ohm. Then the current of LEDs is limited to 100ma, and the transistor gets its saturation level very well.
In this way, the consumption of your circuit lowers ,and you have no problem with...
I suggest you to use a simple op-amp, to get and recognize the voltage level of tel line.
If it is less than 15-20volts, you can detect the hanging off.
Good Luck.
