Question

What is voltage and current?

Answer 1

Voltage and current are two fundamental concepts in electricity. Here’s a simple breakdown:

### 1. **Voltage (V)**

* **What it is:** Voltage is the *"push"* or *"pressure"* that makes electric charges move through a conductor, like a wire. It's the difference in electric potential between two points.
* **Analogy:** Imagine water flowing through a pipe. The pressure at the start of the pipe is like the voltage. The higher the pressure (voltage), the more it pushes the water (current) through the pipe.
* **Unit:** The unit of voltage is **Volts (V)**.

### 2. **Current (I)**

* **What it is:** Current is the flow of electric charge through a conductor. It represents the movement of electrons or charges in a circuit.
* **Analogy:** Going back to the water analogy, current is the actual flow of water through the pipe. It’s how much water is flowing, just like current shows how many charges are flowing through a wire.
* **Unit:** The unit of current is **Amperes (A)**.

### Key Difference:

* **Voltage** is the force that pushes the charge, while **current** is the flow of charge caused by that force.

### Example:

Imagine a battery:

* The battery creates a voltage (push), which causes the current (flow of electrons) to move through a wire when you connect it to a circuit.
