eight. The wheel is analogous to the battery, the vessels Aand B correspond to the two conductors at different levels. Now open the tap G. There is a flow along EF from Ato B, the pressure in A tends to fall, that in B to rise, hence 184 ELECTRICITY [CH. XTII the turbine is now able to propel water… … Fig. 118. from A to B the level of A is above that of B; the differ-ence between A and B corresponds to the potential differencebetween the conductors when in electrical connexion; whilethe difference before the tap was opened gives its value onopen circuit. There are various other forms of battery…
