I’d like to learn more about circuit design/how to build circuits by reading the source
things for making any electronic device, fans, power inverters, converters, heating devices and so on.

What field of Engineering or otherwise deals in this stuff?
Thanks!

For college class

Simple circuits like power supply, charger, op amps – all analog circuitry.

Hai, I am Jagan.I have completed my engineering in the field of Electronics and Communication Engineering.But i have been scheduled to work in the area of soldering the circuits,design and assembling of electronic components in my company.I think that you would have understood.I am scared that in what way that task would match my engineering study and does the job has enough scope to improve? Please guide me…..

This is regarding Electronics R&D Circuits.
It’s must and should to follow some "IPC" standards those are designing circuits.I want that "IPC" standards freely.
Anybody having that standards feel free forward it to my email id.

Me and my lab partner recently completed a lab experiment dealing with transistor data and "the collector characteristic curve for the CE connection". We completed the experiment on our actual workbench and on an electronic circuit simulation program (Multi-Sim). The results on Multi-Sim were twice as much as our actual results. For example 13.582 mA on Multi-Sim was 6.53 mA for our actual results; but both were the same circuits. Any reasons of why this may be happening or troubleshooting ideas are greatly appreciated.

I installed a software that let me use the PC as an oscilloscope , but
it does not mention how to connect the circuits to be tested with the computer an through which port.Does anyone lead me?
I mean how can I connect that cable to
the circuit ?

Hello everyone.

I have to extract the main idea of the following text, but I’m utterly confused. Take a look:

Computers are electronic machines for processing data. Data are pieces or items of information that have been proper prepared so that the machine can work with them. Processing means handling or manipulating the material that has been presented to the machine in such ways as performing calculations, classifying information or making comparisons. A computer is made of millions of electronic devices that can store the date or switch them through complex circuits with differentes functions at incredible speeds.

The collection of devices that constitute a computer are technically known as a computer system. This system consists of functional components, or parts, for input, storage, control, processing, and output. All general-purpose computer systems has these components, but their physical characteristics may vary

The main storage, control and processing components constitute the heart of the computer system. The central processing unit (CPU) has been designed by the manufacturer to control and carry out basic instructions to that particular computer. It is here that the data processing is done. The C.P.U has two components, called the control and arithmetic units. Input and output are handled by machines that are called I/O devices.

What confuses me is that I do not see a real main idea, except for the components of a computer.
So, what do you think is the main idea? (I have to underline it)

Thanks in advance

hi, i drive a 95 dodge stealth rt with an automatic transmission. i bought the car a week ago and started experiencing some problems with the transmission. it starts up and runs great for about 15 min then after i slow down it will give a hard shift down to 1st as i accelerate the car will run through 1st through 2nd shift very hard through 3rd (sometime reaches 5000 rpms) and get stuck in 3rd and will rarely get into 4th. i took it to the trans shop and the 1st thing they did was replace the pulse sensors in the transmission. problem was not solved and i was out of pocket 300 dollars for it. they moved onto the transmissions computer (ecu) and said that it had burnt spots on the circuit board so they wanted me to replace that. I know that sometimes when circuits overheat they have a tendancy of pulling away from the motherboard thus causing the transmission to short out and act goofy… so maybe when the car runs right for about 15 min its because the computer hasn;t reached the temperature to start screwing up idk? should i continue this repair with this shop or just conclude that they are freakin idots and just rebuild the transmission? does the symtoms of the transmission sound like electronic or mechanical? so many questions lol but the quoted me 1800 for a tranny rebuild and idk about you guys but that a buttload of money to drop on 3000 dollar car…

How would I solve the output voltage for these? I don’t know because all the diodes look different. What is the math and formulas used to solve these?

Here is a picture of the circuits.

I’m still have a lot to learn about electronics and I’m getting there but I’m still having trouble understanding a few concepts.

When building an electronic circuit with components, why would you need to purchase a voltage regulator. From what I understand it keeps a voltage constant

But why wouldn’t you just use some sort of resistor combination to get the voltage you need from a load resistor and just build the rest of your circuit off that.

I’m talking about on a small scale like when building circuits on breadboards.
