People will be afraid to say what they really mean. If you don't have enough conviction in your judgement that something is wrong, then it's not worth listening to in the first place. If this di...
It seems to me like the goal of the proposed change is to fight vandalism. I am pretty certain that no online forum has found a way to stop trolls, simply because trolling is one of the ways people...
@Olin. I already read the help/papers doc you pointed out. And that's why I think a part of the papers are very far from the description there (except the "to educate" clause, at the most). As far...
I add my answer here because I think the other answers are incorrect or irrelevant: namely, the answer of Andy is nice after he has redrawn the schematic and changed the problem, answering to anoth...
I saw that equation of reactance is written like this $$I=\frac{V}{|R+X_L j|}$$ $$I=\frac{V}{|R-X_c j|}$$ When there's capacitor and inductor in a single circuit then it is written like : $$I=\...
Your basic problem is that the motor needs some applied power to generate any EMF, but if you apply that power then its not an open circuit test. For a true induction motor you're probably stuck. ...
The problem with cable emissions from HS data and SMPS noise is very common even with UTP and ribbon cable with adjacent grounds on differential signals. I have seen this frequently on HDD testing...
The two-terminal symbol for the attenuator comes from 3 pin potentiometer (pot.) referenced to 0V = "GND" The summing amplifier is always inverting and gives you 3 options for gain which means i...
I am studying for a test in control systems and we have a practical part which is to program a analog computer. Here is a picture of the analog computer: The variable resistor is basically a vo...
This IC is not well suited for the task. MPPT (Maximum Power Point Tracking) relies on matching impedance according to the maximum power transfer theorem. However, in the case of a photovoltaic ar...
For R loads I is in phase with V. For L loads , V lags I up to 90 deg. For C loads, I lags V up to 90 deg. The trigonometric tangent angle is the ratio of impedance: Real to reactive. Your le...
In protocol I2S we have 4 signal: 1.data 2.lrck/fck (frame synchronizer) 3.bck (bit clock) 4.mck/sck (master clock) Not really. IIS really only has 3 signals: bit data, bit clock, and left/right ...
The question below was raised by a "new user". The identity of the "new user" was deleted because it was found to be an alias of an already suspended user: - So, why is the question still active...
If there isn't a VA rating on the label or published in a reliable source, then you have to guess. There are several clues that can be used: Look at the size of the primary wires. That gives you...
I have a HANTEK 6022BE oscilloscope and I'm monitoring three signals with it: FS (Frame sync clock). Pulse. Transfer complete. I'm using two channels of the scope to monitor a pair of these...
This picture describes the behaviour of a single phase transform under resistive,inductive and capacitive loads(from left to right) How what exactly is $V_{1}$ ?Is it the voltage at the primary ...
I have a MOT that is rated 220V-50Hz only and i need to know its maximum operating power i tried to google the reference number but unable to find anything about its power, so how to figure out the...
Question 4 solved: The datasheet lacks the information I've copied from PCM5122:
What we call this opamp configuration? A mess. What's the advantage and the disadvantage of this circuit? This can't be judged without the stated objectives. It might be useful for keepi...
I have been reading about thermal noise in resistors and I have a question: Suppose we have this circuit: Is C2 here to protect the voltage source from thermal noise?
I think these kind of abstract/big picture data communication questions should be on-topic here. Such as the mentioned question about the OSI model. I've been actively pushing for software.codidac...
This is someone trying to rehash a Light experiment with circuits, however I do not think it holds up. Inside a medium, charged particles are subject to Drift Velocity. When you work through the ca...
In this datasheet it says that the minimum resolution is 0.1uA for the 10mA range.What is this minimum resolution?Is it the sensitivity of the multimeter for the 10mA range?
Hello everyone, I have a simple circuit in which I control some LEDs via an MCU and DMG2302UK ( N-channel MOSFET ) The EN pin is connected to an MCU gpio pin that works at 3.3V. The circuit wo...
