An **RLC series circuit** is a type of electrical circuit that contains three main components connected **in a single line (in series)**:
1. **R – Resistor**: It opposes the flow of electric current and converts electrical energy into heat.
2. **L – Inductor**: It resists changes in current and stores energy in a magnetic field.
3. **C – Capacitor**: It stores energy in an electric field and resists changes in voltage.
### How It Works:
* When an AC (alternating current) voltage is applied to an RLC series circuit, the current flows through **R, L, and C** one after another.
* The **resistor** causes a voltage drop that is **in phase** with the current.
* The **inductor** causes a voltage drop that **leads** the current (lagging current).
* The **capacitor** causes a voltage drop that **lags** the current (leading current).
* These three effects combine to determine the **total opposition** (called **impedance**) in the circuit.
### Resonance in RLC Series Circuit:
* When the **inductive reactance (XL)** and **capacitive reactance (XC)** are equal, the circuit reaches **resonance**.
* At this point, the impedance is minimum, and the current is maximum.
### Basic Formula:
The total impedance $Z$ of an RLC series circuit is:
$$
Z = \sqrt{R^2 + (X_L - X_C)^2}
$$
Where:
* $X_L = 2\pi fL$ (Inductive reactance)
* $X_C = \frac{1}{2\pi fC}$ (Capacitive reactance)
* $f$ is the frequency of the AC supply.
