Equivalent Series Resistance (ESR)

Capacitors are connected in parallel in places such as the power supply smoothing circuits. Small value capacitors are connected in parallel as opposed to connecting a single large capacitor. This reduces the effective ESR in addition to reducing the ripple volatge, and allows the circuit to handle higher currents with less losses.
