Hi, I started looking at the Circuit Analysis lab that was included in the J Software release. However, I'm having a problem understanding the basic axioms underlying the treatment..
1. The first axiom is that the algebraic sum of the currents flowing into and out of a "terminal" is 0. I take this as Kirchoff's current law, and have no issue with this. 2. The second axiom states that if the voltage reference is changed, the current is unaffected. <-- This I don't follow. The lab later states that "voltage vectors which differ by a scalar map to the same current". Again, I'm not sure I follow. Given a simple circuit consisting of a resistor, I get (from Ohm's law): V = IR. or when V is a function of I, V = f(I). Now, if I replace the (say) 10ohm reistor with a 5 ohm one, the same current maps to twice the voltage. Any clarification would be greatly appreciated. I tried sending mail directly to the author of the lab, but the mail bounced.
