# **Electronic Devices -
## **1. What is Electronics?**
Electronics is the branch of science that deals with the flow of electrons in
circuits to control electricity.
## **2. Basic Electronic Components**
### **a) Resistor**
- Limits current flow.
- Measured in Ohms (Ω).
### **b) Capacitor**
- Stores electrical energy.
- Measured in Farads (F).
### **c) Diode**
- Allows current to flow in **one direction only**.
- Used in rectifiers (AC to DC conversion).
### **d) Transistor**
- Acts as a **switch** or **amplifier**.
- Types: **NPN** & **PNP**.
## **3. Types of Circuits**
| Circuit Type | Function | Example |
|-------------|---------|---------|
| **Series** | Same current flows through all components | Christmas lights |
