anonymous · Answer

Find the voltages at each node using nodal analysis. I just need to get to the 5 equations and 5 unknowns part and I can take it from there.

anonymous · Answer

@amistre64 you good in physics?

amistre64 · Answer

newtonian basics .... nothing much of anything more advanced.

amistre64 · Answer

what is nodal analysis?

amistre64 · Answer

is V5 a node?  what im reading is that it should be 3 or more branches

anonymous · Answer

I'm not entirely sure how to explain it. This is actually for a MATLAB class, using MATLAB to solve the 5 equations and 5 unknowns when you get that far. I had to result in a youtube video to kinda get an idea of what to do but i still dont think im doing it right.

anonymous · Answer

Yeah v5 is a node

amistre64 · Answer

the direction in or out of a node represents a + or - value ...

anonymous · Answer

right

amistre64 · Answer

how do we calculate for the coeffs of v1,v2,v3,etc?

anonymous · Answer

you get a common denominator and move the constants to the other side and combine like terms.

amistre64 · Answer

direction to node divided by resitance ... and the -5 is the current defined already for V1
