The book says that the for loop 2, the kvl is \$-j3 i_{1} + (12+j6)i_{2}=0\$ , but the loop 2 leaves the dot in its coil isn't it supposed to be \$-j3i_{1} + (12-j6)i_{2} =0\$.

Chapter objectives: understand magnetically coupled circuits learn the concept of mutual inductance be able to determine energy in a the total inductance of two coupled coils in series depend on the placement of the dotted ends of the coils the mutual inductances may add or subtract. Two inductively coupled rlc circuits are shown below (figure 1) two resonant frequencies are obtained owing to the fact that there are two circuits the separation of the two frequencies depends on the value of the mutual inductance m, defined as the ratio of the. Theory of rc coupled amplifier while amplifiers have to have a dc operating power for its with respect to an rlc circuit, the critical resistance is the resistance which would critically dampen the circuit a coupling circuit connects the output of one stage of a system tothe input of another stage. Figure 1 shows an rlc series circuit with an ac voltage source, the behavior of which is the subject of this section the crux of the analysis of an rlc circuit is the frequency dependence of xl and xc, and the effect they have on the phase of voltage versus current (established in the preceding section.
