Details

Markings: Handwritten on labels: "1"/ "43"/ Slide reads in part: "FIG. 36 - Hydraulic analogy of the electric current. If, say 10 gallons of water flow in/ every second into a system of vessels and pipes of any shape, whether simple or more/ complicated as shown in the figure, and 10 gallons flow out again per second, it [i]s evident/ that through every cross section of any vessel or pipe of the system 10 gallons of water/ pass every second. This follows from the fact that water is an uncompressible liquid/ and must be practically of the same density throughout the system. The water moves slowly/ where the section is large and quickly where it is small, and thus the quantity of/ water that flows through any part of the system is independent of the cross section of/ that part. The same condition holds good for the electric current; if in a closed circuit/ a constant current circulates, the same anount of electricity will pass every cross section/ per second. Hence the following law: The magnitude of a constant current in any circuit/ is equal in all parts of the circuit."
