epractically immeasurable. By allowing the current to flowfor a certain period of time a measurable quantity is obtained,which divided by the time in seconds gives the magnitude ofthe effect per second, or the current strength. Keep theswitch closed for about five minutes (5 X 60= 300 seconds),then… … ^wi/^»^Vve^^r Fig. 97.—The Effects of the Current and their Variation with a Variation inCurrent Strength. This is a simple series circuit and the current is the same in all parts of iU 90 PRACTICAL ELECTRICITY. We thus get a series of results of the different effects, allcorresponding to the same…
