LYCOS RETRIEVER 
Capacitor: Current
built 659 days ago
Because the capacitor is used to supply current to the IC it wants to be close to the Vcc pin. The more current the device needs to supply - the larger the cap [or increase the number of same value capacitors].

Connections + and – are conserving electrical ports corresponding to the positive and negative terminals of the capacitor, respectively. The current is positive if it flows from positive to negative, and the voltage across the capacitor is equal to the difference between the voltage at the positive and the negative terminal, V(+) – V(–).
