What is Voltage? A Complete Beginner's Guide What is Voltage? A Complete Beginner's Guide Voltage is a fundamental concept in the world of electricity and electronics. Whether you're a student, a DIY enthusiast, or someone curious about how electricity works, understanding voltage is essential. In this post, we will explore what voltage is , how it works, and why it plays a crucial role in electric circuits. What is Voltage? Voltage, also known as electric potential difference or electric pressure , is the force that pushes electric charges (electrons) to move through a conductor. It can be defined as the potential difference between two points in an electrical circuit. In simple terms, voltage is the reason why electric current flows . It is the energy per unit charge that drives electrons from one point to another in a circuit. The Science Behind Voltage To understand voltage better, let’s look at the atomic level. ...

🔌 Basics of Electrical – Understanding Electricity and Ohm’s Law Whether you're a beginner, a student, or just curious about how electricity works, this guide will help you understand the basic principles of electrical engineering , including electricity, current, voltage, resistance , and the famous Ohm’s Law . ⚡ What is Electricity? Electricity is a form of energy resulting from the movement of electrons through a conductor. In simple words, electricity is the flow of electric charge in a closed circuit . Key Concept: “Electricity flows from the positive (+) terminal to the negative (–) terminal in a complete electrical circuit.” 🔁 Electric Current: Definition and Unit Electric current (I) is the rate at which electric charge flows through a conductor. Unit: Ampere (A) Instrument to Measure: Ammeter Imagine water flowing through a pipe. The amount of water flowing per second is like electric current . ⚡ Voltage: Electrical Pressure Voltage (V) is t...
