Lead-acid battery connected to current wave capacitor
CAPACITOR & CAPACITANCE
capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery. Power factor correction Capacitors are used in power factor correction.
