Summary: The Four Fundamental Elements at a Glance
This table provides a clear comparison of the core purpose and energy handling method for each of the four linear circuit elements we’ve discussed.
| Component | Symbol | Primary Function | Energy Storage Method |
| Resistor | Restricts the flow of electric current. | Converts to heat/light (Does not store) | |
| Capacitor | Stores energy in an electric field. | Electric Field | |
| Inductor | Stores energy in a magnetic field. | Magnetic Field | |
| Transformer | Alters AC voltage levels up or down. | Via a Magnetic Field |
