MEASUREMENT OF HCTCAI ITOUCTABfCE OEAERIAL LOES. To measure the mutual inductance of a pair of parallel lines, connect upas in the cut below. Earth both ends of each line separately, and, to avoidtrouble from earth currents, put a small battery in secondary line with ad-justable shunt as shown.… … the galvanometer needle, when the circuit of the battery is opened with thekey; then, if R = the resistance of the rheostat R as finally arranged,Rt = the resistance of secondary line,C — the capacity of the condenser as finally arranged,and M= mutual inductance, M = CRRX.
