Currently, I enrolled myself in a master's course this fall in the field of Computer Engineering. I am excited to create my microcontroller projects. I want to understand how much complexity is exp...
Will shorting a lithium ion battery cause an explosion? Chain Reaction: The release of flammable gases can lead to a chain reaction, where the heat generated by the short circuit causes even m...
I want 3 SMPS (AC-DC) : Vout/Iout - 5V/20A , 12V/75A , 24V/30A Vin (AC) ~ 220V/50Hz I want it such that I can use Hard & Soft Kill Switches for turning off. Can you help me with the same. I tho...
So here's the thing. Energy doesn't "propagate" as the video suggests. Energy is used. A voltage potential may propagate, but a voltage potential is not energy. Considering the video With the dia...
Since my question didn't get an answer yet, I post this answer as a possible solution. What I'll describe is not meant to be the right way to port an answer from SE network, but just a possible ri...
This is the circuit I have decided to use: The cut-off voltage will be just above 6 V. MOSFETs used are SiRA14BDP and the voltage supervisor is TS831. Maximum current consumption of TS831 is jus...
Looking at the "papers" category, I found that several papers do not fit the very purpose of this category (that's the reason I've not upvoted them). Nevertheless, they are relatively well written,...
I think this site needs to get an aesthetic make-over in order to make users coming back. This may be because I'm accustomed to StackExchange's appearance but to be honest, this site is ugly and u...
I can not upload pictures when I start a new answer to a question (I have no problem when I edit an old answer). When I click the "insert picture" button, nothing happens and I do not see the windo...
When, two months ago, I accidentally found out about the new Codidact platform, I was happy and decided to take part in it. I wanted to mark this event with an interesting question that would arous...
I think that the example question in the O.P. should be re-written as design for manufacturing question (DfM, or some other DfX). Electronics market trends questions should be off-topic. It would...
I have not been present in the hard and very productive work performed by what must now be a pretty spectacular team for the last 10 months. Having returned and found my cherished Electrical Engin...
Microwave ovens work on the frequency they do because that's one of the main resonant frequencies of water molecules. The radiation excites water molecules, which then transfer some of their extra...
Do I need to consult FCC regulations in order to modify a laptop's internal WI-FI antennas to a new housing? This is quite common when modifying laptops to "slabtops". For example, one could 3D pr...
Very short answer - get rid of downvotes on answers; just don't allow them In fact, wouldn't it be a better policy to award upvotes to people who point out errors. That would encourage folk to wan...
I'm designing a PCB for a project. 12 volt input power supply is provided externally, so the user will buy a power adapter, so putting a popular DC jack on the PCB is the best choice.
Hi guys, Can anyone help me please replace the NE555 IC in this circuit by MIC1555. I need to modify also the Voltage to 18v thank you. MIC1555 datasheet NE555 datasheet Edit: The circuit a...
Suppose we have this stream of data.Let's assume the data stream lasts 1 sec. How do we find the bandwidth of the data?Do we Fourier transform the signal in order to find its components in the ...
It all depends on the values of the components:If the system will very slowly decay until the energy of the system reaches 0. If the system undergoes something which will look like a part of...
What is a typical value for capacitance of a real inductor? Does this internal capacitance exist only under AC and not DC?
A diode obeys the Shockley diode equation and for this circuit we have: The current through the diode must not pass a limit so for LTL-307EE we go to the datasheet to find the maximum current be...
After the switch is closed: The general formula for finding the voltage of the capacitor is: where Vf is the voltage of the inductor after infinite time,Vo is the voltage of the capacitor at ...
I recently started working at a construction office in another country. I usually listen to music when working, and I saw a headphone jack in the wall, so I thought it is radio or something, I plug...
Hi guys, I need to calculate the voltage that will center the magnetic field of a coil. The coil gonna be used in an induction heater thank you. Edit: I edited the paragraph because it was misu...
I need a Sine Wave Oscillator circuit that can allow me to control its frequency with a microcontroller. Until now all the topologies that I have found if the frequency is changed, a change in the ...
