Coupled Inductance (cont.)
Resonance (cont.)
M = the mutual inductance,
L1 and L2 = the self inductance of the individual coils.
in cycles per second,
L = inductance in henrys,
C = capacitance in farads,
= 6.28,

interacting, is given by
where M = mutual inductance, expressed
in same units as LA and LO,
LA = Total inductance of coils
L1 and L2 with fields aiding,
LO = Total inductance of coils
L1 and L2 with fields opposing,
of an capacitance is expressed by
where XL = inductive reactance in ohms,
(known as positive reactance),
XC = capacitive reactance in ohms,
(known as negative reactance),
F = frequency in cycles per second,
L = inductance in henrys,
C = capacitance in farads,
= 6.28,
give transformer action, the coupling coefficient is
expressed by,
where K = the coupling coefficient;
(K x 102 = coupling
coefficient in %),
M = the mutual inductance value,
L1 and L2 = the self-inductance of the two coils
respectively, both being expressed
in the same units.

inductive reactance XL equals capacitive reactance
XC is expressed by
also
and
where F = frequency in kilocycles.
where F = frequency in megacycles.
