epressing the key(Fig. 315), a diiierence of poten-tial is established between B andD and currents flow in the circuitsBAD and BED. A and E areat the same potentials at the begin-ning and after the completion ofthe charging of the condensers,since the current in both cases iszero. If then the… … Fig 326 ELECTRICITY AND MAGNETISM CHAP. of the circuits BAD and BED are equal, that is when RjCj = B,A(P- 310). Therefore, when the resistances are adjusted until there is no dis- C B,turbance of the galvanometer on charging or discharging, ^ ~ ■^ When the balance is not attained, the throw is one…
