Connections for Condensers.—Condensers may be connected either inseries or in parallel. If connected inparallel as in Fig. 91 the total capacityis determined by adding together theindividual values, or: C = C-1 + C-2 -f C-3. Thus the jars in Fig. 91 havecombined capacity of .002 + -003 +.004 or .009 microfarad. A series connection is shown intlje diagram.
