The absolute measurement of electrical capacities
Metadata[+] Show full item record
Of the various methods in use at the present time for the absolute measurement of electrical capacities in electromagnetic units, none give the satisfaction desired. Only two of these methods are in common use and they depend on the alternate charging and discharging of a condenser. If the galvanometer used be of a fairly long period, this intermittent current may be considered as a constant current of a definite intensity. The present experiment was undertaken to learn the exact conditions necessary for best results.
