Why does adding a capacitor in series to an AC motor increase its speed? The capacitor does boost the voltage somehow because the input voltage is 132v (mexican mains) and coming out from the capacitor are 230v. This has to do with the inductance because it wont work without the motor. I made...
Hello,
For my project I need to build a variable frequency emitter, with a frequency between 100MHz and 3500Mhz.
I saw some simple RF circuits on the Internet but I don't think they can reach such high frequencies.
Here is a circuit I've found :
I don't need to transfer any information, so...
Read about N-CHANNEL MOSFET’s. Gate and Base act as a capacitor; When gate reaches Threshold Voltage it allows current to flow from Drain to Source terminals by attracting negative charged electrons in between, constructing a conductive bridge.
It is easy to select two oposite charges on DC...
I have an old accelerator board used in the PDS slot of an Apple Macintosh SE/30. The board was manufactured around 1994. I want to replace the electrolytic capacitors but I'm not sure how to decode the numbers printed on the caps. Here's a photo:
As you can see the numbers are:
22
6 A...
Hi there, I'm working on an EMC Control Plan for a product in my company and I'm trying to simplify all the testing processes as we're doing them in house.
So there's one EMC that states the following:
"Secondary power supplies generated by the equipment’s internal DC/DC converter shall respect...
I have bought a capacitance and inductance meter from a 2nd hand shop and there is not manual. So I don't know how to use it. I don't want to damage the device, so I have searched in the net and I have found some information about the mode 6243. My model is 6243+, so I attach some pictures and I...
