ay be measured in the same manner, the sumof all the readings being equal to the total loss on the line,or 10 volts. The watts lost in E F are also three times asgreat as in F G, or three watts and one watt respectively,Formula (62). The total watts generated at point A with onelamp in circuit =:… … MEASUREMENT OF PRESSURE. 233 231. Distribution of Potential in a Circuit.—In the above illustrations the pressure was assumed to be main-tained constant at point A. Consider now a battery ordynamo D, Fig. 207, with an internal resistance (r) of 4 ohmsconnected to one lamp at B, 10 feet distant from…
