It depends on how well you can handle stress. I'm a 3rd year EE student and I had an internship last semester where i worked 20 hours/week and took full time course load and it was definitely a pain. I was extremely burned out by the end of the semester and would not want to go through that...
I am just beginning to learn about diodes and I was wondering if there are any tips to making the correct guess for the diode model. For our class, we use a model that consists of four regions instead of the simple on/off model. basically to figure out what the diode is doing, we insert the...
Thanks all for your replies,
Yes, since we're just starting to learn op-amps, we're treating them as ideal, so i+=0 and i-=0, and when there's negative feedback v+=v-. I guess I should have said that in the beginning =)
That last link the electrician posted is exactly the type of site I am...
Thanks for the reply.
Actually, I wanted to work through the problem by directly using the op-amp and not replacing it with an amplifier model. That's what i meant by "solve these circuit without replacing the op amp with its equivalent ideal amplifier"
Hi, I am just beginning to learn about op amps and I was wondering if there was a way to use the node voltage method (nodal analysis to some) to solve these circuit without replacing the op amp with its equivalent ideal amplifier. To me, it is much faster to use node voltage method than going...
Sometimes solving a circuit by KVL and KCL can be a little difficult. What tips/tricks have you gained from solving such circuits? i know that little tricks won't be as helpful as actually practicing, but they will help nonetheless. for example today i discovered it is not a very good idea to...
Homework Statement
I just had a general question for solving for an unknown current(s) in single or multi-loops circuits. How exactly do we know how many arbitrary currents we need to define for solving the for the currents in the circuit? do we define a current for each loop that is...
thanks all for your input.
maze, i agree with you there, after looking at the solution i always think duh...thats so obvious,why didn't i think of that. I also agree Vanadium because i guess if i truly understand the material, I'd know exactly what angle to attack the problem from.
i...
i don't know what's wrong with me, but i almost always completely understand a problem once i see its solution, but without the solution, i don't get very far with it. has anybody else had this problem? if so, what do you recommend?
ah ok
first mistake was a dumb one
1783.04*74=131944.96 g Ca(OH)2
then for the second part, 131944.96 g is 131.944 kg
from the equation, 1 Ca(OH)2 : 2 HCl (...i guess i also could have done this part earlier when i had mols HCl)
132/2 = 66kg
thanks for your help!
hmm, I'm not too sure what the acid dissociation constants are (as in: we haven't studied that yet(?)) but something i noticed between what i came up with and the answer is is that 66/24 = 2.75. hopefully that's significant...not sure where that comes from though
for the first one:
45*1=.33*x
x=136.4mL
ahh! i see now, subtract 45 from it
for the second one
M = moles/volume
moles = 2.24*796=1783.04mol
mols*(g/mol) = g = 1783.04/74 = 24g
dont get the right answer..not sure what i did wrong there
