6.002x is great! I understand the concept and things are actually starting to make sense!!! Too bad I can't keep up with the math
I've read over 70 pages of the text, watched a few hours worth of videos and some independent research and have concluded that I am fairly thick
I understand KCL somewhat, n-1 independent nodes, all current sums to zero, fabulous.
KVL, though, should be the same with respect to potential, however, setting up the elemental laws prior to analyzing the circuit has me confused. Take a simple voltage divider circuit:
How the devil did they come up with that nonsense?!
First equation is ohm's law expanded - ok, fine no problems here
Second Eq. is substitution of first equation for "I"
but, shouldn't it look a bit different? V1 = R1*I
substitute I with first eq.
V1=R1*(V/R1+R2)
carry through multiplication:
V1=R1*V/R1+R2
cancel out the like numerator/denominator
V1=V/R2
and I know that is not a voltage divider so it leaves me a bit confused.
Any and all advice will be gladly appreciated!
