will being overweight make studying harder?, me being an EE student, i always get easily tired of studying which make me feel like sleeping and when i wake up i didnt notice how time passes by. i can't even carry my heavy body when doing other things like projects and stuff.i also easily get no...

teach me how to increase my luck oh mighty one

is it because the maximum limit of 90 degress phase difference is exceeded? another example: V = 2sin(wt+10) i = sin(wt+210) voltage leads current by 200 degrees?

Urgent question but simple problem:Phase difference Homework Statement What is the phase relationship between voltage and current? i = 5sin(wt+30) V = 10sin(wt+140) Homework Equations The Attempt at a Solution it seems that drawing using cartesian, the voltage is leading the...

so is it really like this "study/ have great marks or you'll regret it" or "improve social skills and minimize study/ sleep well" which is preferable for an engineer knowledge or social skills? and why?

yeah typo: (\frac{z}{\sqrt{p^2 + z^2}})_{-\infty}^{\infty} the problem is differentiating \sqrt{p^2 + z^2} when i keep using LHR it keeps on going back edit: wait did you mean this? \frac{\frac{z}{z}}{\frac{\frac{\sqrt{p^2+z^2}}{z^2}}}} i tihink i get it now just divide both sides by z the...

Homework Statement i was deriving an infinite line of charge formula by coloumb's law: so i got stuck with this integral (since it is in the maths forum) \vec{E}_{\rho} = \int_{-\infty}^{\infty} \frac{\rho_L \rho dz}{4\pi\epsilon_o ({\rho}^2 + z^2)^{\frac{3}{2}}} Homework Equations where...

i need to learn basic stuff about parts of an analog trainer, oscilloscopes, resistors, potentiometers,diodes, transistors... i mean all about electrical engineering experiments and devices... - this book shall orient me how to use these stuffs - this book must guide me on what parts to buy in a...

what kind of diagram? it is already shown: outer current of parallel(2 ohm and 4A) is required

does anyone know a software on how to draw circuit diagrams with white background? i have an LTspice software but i do not know how to convert it into a JPG pic file... what i do is print screen,go to paint and send it to photobucket which is more of a hassle thx (if this has been posted...

Homework Statement Find I in the circuit using the superposition principle Homework Equations superposition: I = i_1 + i_2 + i_3 The Attempt at a Solution for i_1 we neglect the 12V and the 4A sources: (8 + 2 + 6)i_1 - 16 = 0 i_1 = 1A for i_2 we neglect the 16V and the 4A sources: (8 + 2 +...

im an engineer planning to take minor classes at summer... like literature and psychology would you happen to know how many hours of work do you stress out these subjects? i want to study in advance major subjects at summer in preparation for the following semester.

i am one with no social life... but i need to improve my social skills How will i do that? read the news?, improve your vocabulary?, watching TV?, read a book about mannerisms? etc...?? i would like to hear about someone's opinion of this...
