Due to KVL, sets of circuit elements between two nodes are in PARALLEL and have EQUAL voltage drops: Δܸ ோଷ ൌΔܸ ோଶ ܽ݊݀ Δܸ ோସ ൌΔܸ ோହ ൅Δܸ ோ଺ Δܸ ோହ ൅Δܸ ோ଺ ൅Δܸ ோ଻ ൌΔܸ ோଶ Moving the multimeter probe to any part of the wire within a given red circle will not significantly influence the measured voltage. Neglecting the relatively small electrical resistance of the “wires,” the areas inside the circles can be considered “nodes.”

CLASS PROBLEM: Consider the circuit below where R 2 is a variable resistor (a resistor whose value can be changed by turning a knob). We would like to understand the variation of the total current leaving the power sources as a function of R 2 . a. Redraw the circuit so it is easier to tell which resistors are in parallel. b. Develop a function for the current I in terms of the resistance R 2 , and embed this function into Mathcad. c.
