I am going to change a few things and repost with an update.

What is it that you mean? The floating ground? Yes I agree TINA has been giving me issues. Sometimes the outputs are different and all I do is delete a connection and redo the same connection and it changes everything. I found that out this morning.

Hello all! I hope I am posting this in the right place. I am looking for some help on the following circuit. Basically I am doing a relay application using one of TI's chips. Below is the reference design from an app note along with my actual circuit modeled in TINA. The main function is that...

Homework Statement Select all of the following which are possible combinations of Lz and θ for hydrogen atoms in a d state, where Lz is the z component of the angular momentum L, and θ is the angle between the +zaxis and the magnetic dipole moment µℓ due to the electron's orbital motion...

so this being said since the top connection is to the left the bottom is to the right? & I guess what I am Really confused at is which one is positive. The tutor explained to me both the connected terminals where positive on top and negative on the bottom. I am more lost on determining which...

Chegg has this. This because the power A > 0 so it is being delivered power to A and it flows from negative to positive? Is my assumption correct? thank you

Homework Statement I am having trouble understanding PSC. Please help on this question. Teach me like I am 5. My tutor couldn't break it to me. (SEE ATTACHED) and find whether the power is being given or taken Homework Equations p=vi p=-vi The Attempt at a Solution I can't...

I had done so much work I didnt want to type it and was going to upload a picture, But indeed I figured it out.. Using U sub with U = xy^2 du = 2xy and x was a constant so it was factored out leaving everything peachy!

Homework Statement Attached below Homework Equations The Attempt at a Solution So I cannot figure this out. Would this be integration by parts? or by substitution.. It provides me with an answer but no reasoning behind it and I cannot figure it out =/

Ahhhhh I see it now! Thanks a lot! This helps a lot this section because I couldn't put the pieces together!

Well I'm pretty retarded lol But what about the greater than or equal to signs? And why weren't they reversed? Like from elementary you learn to flip them if it's anything with a negative number.

Homework Statement See attached image Homework Equations they are provided in the image. I see the domain is used The Attempt at a Solution I can't figure out how they went from step one to step 2. where does the -81 come from and the 9 multiplied to the function in the middle. I...

Ahhhhh i see! Thanks! Silly question I know but Id rather ask now and understand it rather than not know at all!

On the picture it depicts it. An in the paragraph starting with "some of the electrons" sentence says they are unbalanced. I'm just a little confused on it

Can anyone explain this excerpt to me? I'm lost on how the positive and negative charges push each other away instead of attract. Thanks! P.s I think this goes in this forum.
