RLC series circuits combine resistors, inductors, and capacitors to produce frequency-dependent behavior. Their overall impedance is determined by both the resistive and reactive (inductive and capacitive) components. At resonance, when the inductive and capacitive reactances cancel, the circuit exhibits minimum impedance and maximum current. The phase angle between voltage and current, encapsulated by the power factor, is critical for understanding real power consumption. Mastering these concepts enables the design of effective filters, tuners, and efficient power systems.

What is the value of the magnetic flux at coil 2 in Figure 23.56 due to coil 1?
What is the value of the magnetic flux through the coil in Figure 23.56(b) due to the wire?
Referring to Figure 23.57(a), what is the direction of the current induced in coil 2: (a) If the current in coil 1 increases? (b) If the current in coil 1 decreases? (c) If the current in coil 1 is constant? Explicitly show how you follow the steps in the Problem-Solving Strategy for Lenz's Law.
Referring to Figure 23.57(b), what is the direction of the current induced in the coil: (a) If the current in the wire increases? (b) If the current in the wire decreases? (c) If the current in the wire suddenly changes direction? Explicitly show how you follow the steps in the Problem-Solving Strategy for Lenz’s Law.
Referring to Figure 23.58, what are the directions of the currents in coils 1, 2, and 3 (assume that the coils are lying in the plane of the circuit): (a) When the switch is first closed? (b) When the switch has been closed for a long time? (c) Just after the switch is opened?
