How can I calculate how fast I can switch the mosfet? I have the 8 kohm pull up so I think that impacts my charging discharging time? But how do I go abotu calculating it.

Okay, awesome. I was thinking if there is a easier way then starting from scratch, but maybe not. So firstly I have to code a graphical interface like paint. Store this code in a microcontroller. Can you guys recommend microcontrollers I could use to program a visual interface software which...

Sorry for the vague post, but I am having trouble asking my question. Not sure how to ask it due to my lack of knowledge. Okay, so, If I open a dvd player or receiver or any box, I am guessing there is a video card which connects to the tv (the video card has the outputs like s-video etc.)...

I am interested on working on a small home project. I want to build a device that will connect to a TV (through s-video or any video output). I was just thinking about it and was wondering what hardware would be required to do this? I am just a beginner but I want to learn more.

anyone?

I had a question about the final value theorem: lim sF(s) S->0 = lim F(t) t->infinity I was told I can only use this if I know that a final value exists for f, or in other words that f(infinity) exists. How can I check if it exists? If I have F(s), the only way...

That wording is a bit confusing since you are saying you are overloading the transformer, yet I am applying LESS load on the secondary side. I guess when someone says overloading the transformer, you have to look at how much power is needed in the secondary side. So my question is, if I...

1. Lets say I put a resistor with a value 1 ohm on the secondary side.. what happens? [PLAIN]http://img256.imageshack.us/img256/9639/67417248.jpg The thing is, in theory I just calculate the Z value and find out what it is. BUT, why does it have to be that. Practically, what would happen if I...

So in other words, the power generated is not constant. It keeps adjusting according to how much is in use?

I had a question about power generation that was confusing me for awhile, I hope someone can clear it up. A specific amount of power is generated by the power plant. If I am not using all the power that I can use, where does it go? is all the power always in use? if it is not in...

Isn't the third prong there incase the live wire gets loose and touches the device's case. So if you touch the device you will not getting shocked as the third prong will create a short allow the current to flow through. That is what I always thought the third prong was for :S.

Can someone tell me how DIP switches work in circuits? I had an issue with a printer and saw that I had to change one of the DIP switches to change a setting. How do they work in a circuit? I remember working in VHDL and there were also switches on a FPGA board (I don't know if those were also...

if you analyze the loop where the open circuit voltage exists, you get Kirchoff Voltage Law (1) -VS + VR2 + VR1 + VOC = 0 Right?What is the voltage across R2 (VR2) and R1 (VR1). Since no current passes through R1 and R2, as said before, there is no voltage drop across them. Therefore solve...

Yea, I just asked someone here and they said it meant that it can work with both 24 V DC or AC, since the RMS of the 24 AC will be enough to run it. thanks :)!

I am a student trying to learn about PLCs. I was buying a light (beacon) to install on my PLC and had a question about the output voltage. On the PLC I saw that the outputs are 24 V DC. On the beacon I am ordering, the options are: 12V AC/DC Full Voltage 24V AC/DC Full Voltage 120V AC...
