### Lesson Introduction: Ohm's Law for Grade 9 Technology

**Welcome, Class!**

Today, we are going to dive into one of the fundamental principles of electronics: **Ohm's Law**. Understanding this law is crucial for anyone interested in technology, electronics, and electrical engineering.

**What is Ohm's Law?**
Ohm's Law is a simple mathematical equation that explains the relationship between three key components of electrical circuits: **Voltage (V)**, **Current (I)**, and **Resistance (R)**. It is represented by the formula:

\[ V = I \times R \]

Where:
- **V** is Voltage, measured in **Volts (V)**
- **I** is Current, measured in **Amperes (A)**
- **R** is Resistance, measured in **Ohms (Ω)**

**Why is Ohm's Law Important?**
By understanding Ohm's Law, you’ll be equipped to analyze and troubleshoot electrical circuits. This knowledge is not only applicable in everyday technology, such as smartphones and computers but also in various fields including engineering, physics, and renewable energy.

Throughout the lesson, we will:
- Explore the concepts of voltage, current, and resistance
- Learn how to calculate these values using Ohm's Law
- Perform hands-on experiments to see Ohm's Law in action

**Real-World Connections**
Have you ever wondered how the devices you use every day operate safely and efficiently? Ohm's Law is behind the design of circuits in everything from household appliances to complex computer systems. Understanding this law will help you appreciate the technology around you and empower you to create your own electronic devices.

So, let’s get charged up and ready to unlock the mysteries of Ohm's Law! Are you ready? Let's go!
