Why do some UPSs have both Volt-amp and watt rating? According to APC, the connected load shouldn't exceed the UPS's VA and watt rating. Why? If I had a UPS with 1000VA and 500W rating, why can't it power a load consuming 1000VA @ 900W? If a UPS can output 1000VA, why does it care how much...

My friend bought a condo last winter and now in cooling season her AC unit (water source heat pump) is faulting-off sporadically. I've done some basic troubleshooting, and the unit is showing a over/under voltage fault on its LED. It's a 208V/1ph unit. According to the manual, the controller...

Hi, I was experimenting , after doing some reading, with 'Net Share' in my Windows 10 Command Line, on my PC, which I'm not using as a server, i.e., I'm not running ( nor do I have installed) Windows Server nor other server software. The output was: Share name Resource...

I am trying to simulate the active converter, I have seen in you tube video the output of the grid 3 phase voltage is given to LCL filter, the output of the LCL filter is then given to the half bridge section. I assume that the output of the LCL filter is a DC instead of the sine wave, as it is...

I have screenshots, but I'm not willing to share the contents of my Documents folder in a public forum. Is anyone willing to assist me? Additionally, I have "cd" aliased to "HOME=~/Desktop cd" in my ~/.bash_aliases file, if that helps. I might have also had two terminal emulator tabs open while...

Hi everyone. In most cases when torque and lever arm are being discussed, it is the angle between the force and the arm that matters (like in the following picture). However, non of the articles that I have read so far have mentioned anything about the distance between force and fastener being...

can someone check, if i calculated the output voltage correct? i used virtual ground because V+-input of the op amp is 0 --> V- input is then also 0.

What are the most important fission products should I include/care about that comes out from the MCNP output?

My log burner is just too powerful for everyday use. It is spec'd at 5kW and has an area of about 200X400mm. It's a single fuel design with no bottom vent. The air control is quite clever. It has an 'air curtain' supply which comes down from the top and two adjustable slots in the doors to get...

I am interested on how Feynman diagram is formed from a differential equation model of particle interaction wherein the incoming particles are not bound (e.g., separated neutron, proton and electron) and one or more of the outgoing particles are bound (e.g., hydrogen atom). However, I had never...

The standard output waveform of a photomultiplier tube has a "negative" pulse, like below. Why is the amplitude negative?

THE ANSWER IS GIVEN: 6V, but according to me as the positive terminal is grounded the negative terminal will be virtually grounded (0V), from ohm's law (applying to the two series resistance) it is expected that Vo is 0V! I don't know where I am getting wrong!

I need help with part (a)... I know that the root-mean-square voltage is the dc-equivalent voltage for an AC waveform and what my book labels "##V_{dc}## is actually the average voltage. Hence I am assuming the question is asking me to find ##V_{rms}## ... Is my assumption that the...

I am ~180lbs and have been lifting weights for about 12 years straight. I have also been running 3-4 times per week for the last 8 ish years. I have recently gotten into cycling, and noticed at the gym on the Schwinn "spin" bike, I will have peaks of around 400-500 watts, but it's definitely...

Is this design correct?

I obtained the following result: ([(A xor B) xor 0]* AC)' ([(A'B + AB') xor (0)]*AC)' [([A'B + AB']*(0)' + 0)*AC)]' [(A'B + AB')*(1)*(AC)]' [A'ABC + AB'AC]' [AB'C]' A'+B+C' the solution to this problem is getting a different answer, I don't know why this solution isn't inverting the output AB'C

This is an issue I've been stuck on for about two weeks. No matter how many times I take this derivative, I keep getting the same answer. However, this answer is inevitably wrong. Please help me to understand why it incorrect. To start, I will define an input matrix ##X##, where ##n## is the...

Hello, I am looking to build a small RF circuit to drive a pan/tilt antenna tracker. The tracker will have 3 identical directional antennas arranged in a triangular pattern and will use RSSI to follow the signal (obviously) horizontally and vertically. My idea is to design a single PCB...

The connections are as follows: The "D" pins are connected to the data bus, the "Q" pins to the device, the "E" control to the block address decoder, the "OE(bar)" to ground. Am I right?

I had a bunch of questions regarding the feedback component as well as the feedback mechanism itself. 1. I am using the attached schematic as reference for my design. As per the LM2576 module data sheet, it can handle a maximum current of 3 A whereas I need the IC to handle at least 15 A...

Hello, I am new to engineering first year! I was wondering what "Tie pin 1 high to enable the output" My boss asked me to look at a crystal and asked me to do a small PCBA in PCB Express, but I am not sure what "high" is, is "high" tied to the +5V supply or is he asking for me to drop a pullup...

Hey! 😊 I want to draw a circuit that has four inputs a, b, c, d, and which gives the value $[(a \lor b) \lor (c \lor \neg d)] \land (c \land \neg a)$ at the output, using exclusively the NAND gates with two inputs. Hint: If you connect the two inputs of such a NAND gate, you get a so-called...

Hello everybody! I was wondering today if physically, it'd be possible for the world to develop an air conditioner without an outdoor heat unit? I know this seems to violate the second law of thermodynamics, but the known version of the second law thermodynamics only consider this is impossible...

Hi, I was just working through this gearbox problem and the answer key has different results to mine. I thought that I should show my working to see where the error is on their part or mine? This is the gear box (for reference, ## N_s = 32 ##, ## N_p = 16 ##, and ## N_r = 64 ##) My attempt...

I had previously solved this using Root Mean Square method by integrating the value of voltage from t=0 to t=T/2 and then from t=T/2 to t=T.Answer was Vo/2½.Yesterday I found this question👇🏾 if I followed the previous approach then: 5 volts is not even in the option. How can I find the DC...

I learned that solar panels have their maximal power output at a particular voltage and current level. If we want to get the max power, we have to connect a load with a specific resistance. However, in reality, how does the solar plants solve this problem? I guess they won't allow the power...

In optical communications, one of the modulation methods is to control the optical power (Simplest case, for example, bright = bit 1, dim = bit 0). I learned that we can achieve this by a Mach-Zehnder modulator (MZ modulator). Simply speaking, the principle of MZ modulator is to split the input...
