A bullet list: Step-down transformer (12-0-12), 4 PN diodes (1N4007), Capacitor (1000µF), LED, Resistors (1kΩ), Breadboard, Connecting wires, Multimeter, CRO (optional).
A rectifier is a device that converts AC to DC. Since a diode allows current to flow only in one direction (forward bias), it can be used to block the negative half-cycle of an AC signal, effectively "rectifying" it.

Before diving into the project details, it is important to understand why this topic is so crucial. Semiconductors are the foundation of modern electronics. From the smartphone in your pocket to the sophisticated systems in satellites, semiconductor devices like diodes and transistors control the flow of electricity. A bullet list: Step-down transformer (12-0-12), 4 PN
The behavior of semiconductors is explained by the :
Built using combinations of diodes and transistors to perform logical operations (AND, OR, NOT) in computers. 7. Conclusion Hand-drawn or neatly printed diagram
P-side connected to negative, N-side to positive. The depletion layer widens, preventing current flow (except for a tiny leakage current). 6. Applications of Semiconductors Rectifiers: Devices that convert AC to DC.
