Ever wondered why your phone's screen lights up when you touch it?
Imagine you're holding your phone, ready to play a game. Suddenly, you tap the screen, and it lights up instantly.
Your phone's screen lights up because of electric charges moving when you touch it. This movement creates an electric field that the screen's sensors detect, making it light up.
Example
When you touch the screen, the electric field changes rapidly, signaling your phone to respond.
Remember this
The electric field created by your touch is what makes the screen light up.
