Compact “ultracapacitors” with capacitance values up toseveral thousand farads are now commercially available.One application for ultracapacitors is in providing power forelectrical circuits when other sources (such as a battery) areturned off. To get an idea of how much charge can be storedin such a component, assume a 1200-F ultracapacitor isinitially charged to 12.0 V by a battery and is then disconnected from the battery. If charge is then drawn off the platesof this capacitor at a rate of say 1.0 mC /s, to power thebackup memory of some electrical device, how long (in days)will it take for the potential difference across this capacitorto drop to 6.0 V?
