⚡ What is Voltage & Current? | Roles in Power System (With Diagram)
In the world of electricity and power systems, Voltage and Current are two fundamental concepts. Understanding them is crucial whether you're a student, an electrician, or just a curious mind. 🔌 What is Voltage? Voltage (V) , also called electrical potential difference , is the force or pressure that pushes electrical charges (electrons) through a conductor. Think of it as the pressure of water in a pipe —it doesn’t move the water by itself but creates the condition for it to flow. Unit : Volt (V) Measured By : Voltmeter Formula : V = I × R V = I \times R V = I × R 🔋 What is Current? Current (I) is the flow of electric charge in a circuit. Just like water flowing through a pipe, electric current is the movement of electrons through a conductor. Unit : Ampere (A) Measured By : Ammeter Formula : I = V R I = \frac{V}{R} I = R V 🔁 Difference Between Voltage and Current Feature Voltage Current Definition Pressure that pushes electrons Flow of elec...
