English to Italian Tech/Engineering Engineering (general)

Come tradurreste in questo caso "strength"? "resistenza" oppure "intensità"?

"As a consequence, and as can be understood from Figure 5, by carefully matching the coils, the strength of the feedback connection, and therefore the controlled delay of the closing of the movable and fixed electrical contacts, arcing and thus contact erosion energy is reduced or eliminated, shown by hatched portion X1 in Figure 5, prolonging contact life or improving endurance life."
