XL(inductive reactance) = 2 pi f L where pi= 3.142(a constant), f=frequency and L=inductor value. From the formula XL=2pifL
L=XL/2pif The more you increase the frequency (f) the less the inductor value and size.
XC=1/2pifC therefore C=capacitance = 1/2pifXC. As in the inductor, the more the...
Yes. I don't mind being your oversea agent. The issue is I need to know what it is used for. I can't promote what I don't know much about. give me details and bet you I will advertise for you here.
zeiss objective for operating microscope
Hello! Friends,
I am trying to fix a carl zeiss surgical/operating microscope and I find out the objective lens is missing. I have tried to contact them through their website but no success. My aim is to use any suitable objective lens that can perform...
Please, I need suppliers/manufacturers and/or catalog for ferite core transformer. I shall be in regular need of this component for fluorescent inverter for small production unit/business. Thanks a lot.
oxcimeter
Pleaqse I need help on the principles of operation of a pulse oximeter and acircuits or practical schematics to demonstrate the working principles. Thanks
To construct an electrophoresis power supply unit is not a problem to me, but how lab. scientist use the power pack to obtain the expected results. Please intimate me on the theory of electrophoresis.
I need ideas which may lead me to develop a system whereby two pipes of the same diameter can be joined together. Schematics in this is welcome. Thanks a lot.
convert square to sine wave
Re 12v-220v modified sine wave inverter reply by didiet78. I appreciate your reply to my request. I have look through the circuit diagram but the text is written in a language i don't understand. The transformer in the inverter schematics, is it not a laminated core...
I want to be able to bring to boil by electronic means small quantity of water in which two tiny electrodes (positive electrode and negative) electrode is immersed.
I think if high frequency current is passed through the electrodes it should bring the water to boil. Can anyone assist me with...
You can use a fixed 12v power supply unit schematic with power transistors with pass resistors in parallel.The schematic diagram for the fixed power supply unit you can get from www.aaroncake.net.
Iam working on a project by which heat will be generated in a medium, be it liquid or solid (non conductor) placed within two tiny electrodes.
At different times, one of the electodes should be able to cut a piece of bar soap placed in between.Can anyone help with this project?
convert square wave to sine wave
I have been working on aninverter but I found out the inverter could not power on a television or computer monitor.I think probably the problem is due to the characteristics of the output waveform,which is square.Please how can I solve this problem?[/url]
