On the pictures, one is the problem and another is a solution in a solution manual. I'm curious why Vsb = Vin = 0.2, since Vin is across the source and ground, but Vsb is across the source and bulk (substrate).

Thank You

I have this assignment for a Diploma I am studying and I'm a little stumped. I feel like the method to working it out is right in front of my face but for some reason I can't see it. Here is what it says in the assignment:

------------

The Radio system will be powered by a D.C. Power Supply, with built-in Back-Up Battery facility. The Power supply is rated at 13.8 V, 25A 100% Duty Cycle.

The Radio System consumes 650 mA when quiescent; 1.75 A when receiving, and 7.75 A when...

Could you please help me out on how to connect the following circuit on a breadboard, I'd really appreciate some video links which can help me understand how to interpret the questions and understand the logic behind connecting this circuits.

I'm new here so I'm not even sure if this types of questions are allowed....Anyways, Here's the experiment:

I was wondering how can I change the fully depleted soi code in silvaco to have a finfet

thank you]]>

Thanks in advance.]]>

If water is available and gas is available the system should continue operation and if otherwise the system should short down so as not to damage the rotating machine .

Very urgent pls]]>

Can someone give me an electrical schema or any advice?

Thanks.]]>

While I am watching this video of GreatScott! **At 3:21 ,

I took up my calculator and calculate the power by using P=(V^2)/R, and the answer is 72W.

- This happens due to the voltage across the Peltier may not be accurately 12V as there's Req=Rpeltier+Rwire, is my statement correct?

- 72W and 32W is totally a huge difference, why?

- So, when to use P=(I^2)R and P=(V^2)/R to calculate power loss?

Thanks in advanced.

So im realy stuck trying to understand PLL's in terms of the calculations ive been looking at. This is a good example of the type of thing - taken from phase locked loops by Roland Best

OK so the U(t) signal seems to tell me that its a standard sine with a changing "phase"

The example and figure show a linear frequency increase from t=0

I have no idea what delta*w^dot means in the notation. I have never seen this before. it seems to be saying the change of gradient? anyway...

Then I...

The question is:

In an AC circuit the voltage can be described using a sine wave with the equation:

I need to work out

a. the frequency

b. the amplitude

c. the relative phase

I know that the amplitude is 150v so that is (b) taken care of, I am now unsure how to work out the following despite scouring the internet and my reading...
