First clarify where this leakage current will be flowing. You seem to think that some parts of the solar panel will generate a small current thru the rebar into the ground, but where is the closed...
The magnetic field will always be strongest in the middle of the solenoid. It will be slightly less at the ends of the solenoid and, it will be a lower value on the outside of the coil half way bet...
If you're referring to this Wikipedia page then the topology has a negative output. In that case, the problem as you have it stated in the OP, is misleading: it should be Vo=-20. With that, extract...
That fourth connection is the bulk/body/substrate connection: - Image from here. On a normal 3 terminal MOSFET the "body" is connected to the source. On your device, the 3 n-channel MOSFETs shar...
Is the Thevenin's Theorem being applied incorrectly for the circuit ? It's being applied inaccurately. The final Thevenin voltage should be 2.782 volts (rather than your calculated value of 2....
No, a resistor divider is not appropriate, at least not if you want to get all the information from the STAT pin. In addition, that chart in the datasheet is incomplete at best, or downright misle...
Unfortunately the frequency legend on your graphs are too small to see, so we don't know how the left and right graphs relate to each other. However, what is certainly going on in the left graph i...
I want to design a simple battery charger using MCP73831/2. This chip has a 3-State state pin according to the table below: I have a 3.3V MCU and I want to connect this pin to a GPIO. The MCU is...
Since your noise has "unknown characteristics", you should do low pass filtering in analog before the discrete sampling of the A/D. The two parameters that matter are the frequency content of the ...
I think you can make a pretty good case for the spike being caused by the addition of the 100n and 10n capacitors: - I assume that the solder blobs between capacitors introduced a series indu...
This question is related to my previous question. I want to drive a brushed DC motor using H-bridge. To power the motor two 18650 cells will be used in series. The issue is that I want to limit th...
Nevermind (for now) what Wikipedia or anyone else says. Stop and actually think about it. One problem with the question is that is says "buck-boost" but doesn't otherwise define that. A buck-boo...
I have a Rigol DS1104 oscilloscope. Last week I stood up quickly from my table and saw a spike on the scope. Right now all the channels have a DC offset when probe is connected to ground or unconne...
Lower ESR can sometimes be a reason, as you say. However, most of the time the advantage is a wider frequency range over which the combined capacitor has low impedance or low dissipation. The fre...
This page: https://electrical.codidact.com/help/papers says: A paper is more than just a few paragraphs, and more in depth than most answers. The starting level for a paper is about a detailed a...
Inside a op-amp after the stage where the differential signal is converted to single ended , there is further amplification of the DC signal.For AC signals there is a capacitor parallel to the tran...
I have generated flyback convertor schematic by TI's Webench Power Designer. Parameters: universal AC input (85-265V AC) 5V, 2A output isolated UC3843A controller Basically I understand f...
I'll try first to give a general introduction to the problem, then I'll switch to your particular questions. Passive linear components, like capacitors, inductors or resistors are not ideal. For t...
In the field of DC/DC conversion, one can build a synchronous DC/DC converter (also referred to as synchronous rectification). This practice involves replacing a diode with a MOSFET switch. As far...
PCB antennas are not designed by electrical engineers, but guys with pointy hats and wands They use trial and error after starting with the result of some mystic ritual including lots of mumbling ...
Try searching for "multiple outputs flyback". Basically, you can't control each, individually, instead you make the voltage feedback as the average between the outputs. Here's a quick'n'dirty test ...
After reading the suggestion about conferences, I came up with a loose brainstorming idea... What draws engineers to fairs/conferences (apart from free lunch)? Most definitely technical speeches/sl...
Please let me know if there is anything wrong with this logic. So far so good. The voltage clamp (3 zener diodes for European IS category iA and two for category iB) is the limiter on voltage ...
Some issues: Physical robustness. Some probes just are built better than others. How well does the clip pop off? How well does it stay on when you don't want it to pop off? How solid is the ho...
I am designing a PCB with somewhat limited space. To save space, I am placing some vias on component pads. However, I am not sure if this is a good practice in PCB design. As far as I understand, t...
