Master RLC circuits, step-by-step.
A series RLC circuit combines a resistor (R), inductor (L), and capacitor (C) in series. Its behavior is dominated by the interplay of resistance and reactances to AC voltage.
↳ Understanding R, $X_L$, and $X_C$ is crucial for analyzing RLC circuit response.
Inductors resist AC current differently.
Inductive reactance is the opposition an inductor presents to AC current, increasing with both inductance and angular frequency.
↳ Inductive reactance is directly proportional to frequency and inductance.
Capacitors resist AC current uniquely.
Capacitive reactance is the opposition a capacitor presents to AC current, decreasing with increasing capacitance and angular frequency.
↳ Capacitive reactance is inversely proportional to frequency and capacitance.

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which formula gives the impedance of a series RLC circuit?
Beginner$Z = \sqrt{R^2 + (X_L - X_C)^2}$
Impedance combines resistance with the NET reactance $(X_L - X_C)$ as a phasor triangle, so $Z = \sqrt{R^2 + (X_L - X_C)^2}$.
A series RLC circuit has $R = 100\,\Omega$, $X_L = 188.5\,\Omega$, and $X_C = 265.25\,\Omega$. What is the impedance?
Intermediate$126.06\,\Omega$
$Z = \sqrt{100^2 + (188.5 - 265.25)^2} = \sqrt{10000 + 5890.6} \approx 126.06\,\Omega$.
Which component in a series RLC circuit dissipates average power over a full cycle?
BeginnerThe resistor only
Inductors and capacitors store and release energy but dissipate none over a full cycle; only the resistor converts energy to heat.
In a series RLC circuit the phase angle $\phi$ is negative. What does this tell you?
IntermediateThe current leads the voltage and the circuit is capacitive
A negative $\phi$ means $X_L - X_C < 0$, so $X_C > X_L$ and the current leads the voltage — a capacitive, leading circuit.
