f its heatingeffect. The thin beam of ka-thode rays is deflected into ametallic cup A (Fig. 408) by means of a magnet. If N corpuscles enter the cup per second, then Neis the charge given to the cup per second. Calling this Q, we haveNe = Q, and Q is measured by the rate of change of potential,… … Fig. 408. 474 ELECTRICITY AND MAGNETISM ohap The rays on entering the cup fall upon one junction of a thermalcouple in series with a galvanometer, so that the rate of rise in tempeia-ture of the junction due to the bombardment by the rays could bedetermined. If, then, the heat capacity of the…
