Absorptive Capacity: Scale Development and Implications for
he concept of Absorptive CAPacity (ACAP) has conti-nuously grown in importance since Cohen and Levinthal (1990, p. 128) first defined it as "the ability to value new external information, to assimilate it and to apply it to com - mercial ends". Based on the work of Zahra and George (2002) ACAP is nowadays perceived as having four dimensions

23.2: Reactance, Inductive and Capacitive
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase angle. Since a capacitor can stop current when fully charged, it limits current and offers another form of AC resistance; Ohm''s law for a capacitor is [I = dfrac{V}{X_C},] where (V) is the rms voltage across the capacitor.

The current thus decreases from its initial value of (I_9 = frac{emf}{R}) to zero as the voltage on the capacitor reaches the same value as the emf. When there is no current, there is no (IR) drop, and so the voltage on the capacitor must then equal the emf of the voltage source. This can also be explained with Kirchhoff''s second rule (the loop rule), discussed in ...
