M, add the results, and you find you get the apparently impossible result that the arithmetical sum is greater than the line voltage, E. Now if these two devices are connected across a direct current circuit and the drop on the lamp added to Fig. 390. the drop on the coil the sum of the two would,… … ALTERNATING CURRENTS. 447 current to the terminals, T, Ti, no current would flow unless the insu-lation broke down. Jf a galvanometer, (I, is connected in the circuit,it will be noticed that just after the pressure is applied a currentwould flow for a short interval ; also if the terminals, (/and…
