y of one or two cells controlled by a key K, all being connected as shown. The resistance C is varied until the galvanometer shows no deflection when the keys K and 8 are closed in the order named. If the key S should be closed before K, or at the same moment, the inductive effect might produce a… … Fig. 73. Wheatstone Bridge Diagram
