ECE 110 M.-C. Brunet IV Characteristics Handout 7 IV Characteristic: What is it? C + - v I It is the equation I = f(V) ( is the relationship between I and V ) For one particular connection of the circuit C, we get one point (v, i) on the graph, and i=f(v) I f(V) V X v i some circuit C V= v I= i + - Linear IV I f(V) is line! M.-C. BRUNET ECE 110 UIUC 7.1 I = a x V + b V a line!
