+# 🔌 N-Channel MOSFET: Overview
+
+An **N-channel MOSFET** (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor that controls current flow using an electric field — it's a three-terminal device with:
+
+- **Gate (G)** — controls the transistor  
+- **Drain (D)** — where current flows **into**  
+- **Source (S)** — where current flows **out of**
+
+When a positive voltage is applied to the **gate** relative to the **source**, the MOSFET turns **on**, allowing current to flow from **drain to source** (D → S).
+
+## ⚙️ Common Uses
+- Power switching in motor drivers  
+- Voltage regulation  
+- Signal modulation  
+- Digital logic switching

+# 🔁 Use in an H-Bridge Motor Controller
+
+An **H-bridge** is a circuit used to control the **direction** of a DC motor. It consists of **four switches**, typically implemented with N-channel MOSFETs:
+
+## H-Bridge Configuration:
+
+![H-Bridge Circuit](./n_channel_h-bridge_motorcontrol.png)
+
+
+- **Q1 + Q4 ON** → motor spins in one direction  
+- **Q2 + Q3 ON** → motor spins in the opposite direction  
+- **PWM control** on low-side N-MOSFETs allows speed control  
+
+Because N-channel MOSFETs conduct easily when their **gate voltage is higher than the source**, they're ideal for **low-side switching**. High-side use may require **gate driver circuits** to boost voltage.
