et P, Q be twosections of the tube; if tlie tube remains full, since the wateris incompressible, the quantity of water which crosses P inany given time is equal to that which crosses Q in the sametime; if the tube were full of air this would not necessarilybe the case, the compression of the air… … In this respect the flow of electricity when a steadycondition has been reached resembles that of water. Carefulexperiment shews that the current at P is always equal totliat at Q, Hence the current in a conductor is measured bythe quantity crossing any section of the conductor per second. 109.…
