Static electricity
Introduction:
• Definition - Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away as an electric current or by electrical discharge.
Formation and Discharge of Static Electricity:
Static electricity happens when tiny particles called electrons move from one object to another, usually when two things rub together or touch and separate.
Here’s the explanation in simple but strong, clear words:
Every object has tiny electric charges inside it.
When two different materials rub or press against each other, electrons can jump from one surface to the other.
The object that gains electrons becomes negatively charged.
The object that loses electrons becomes positively charged.
These charges stay stuck on the surface because they have nowhere to go, especially if the object is an insulator (like plastic, rubber, or wool).
When the charged object finally touches something that lets electricity move (like metal or a person), the built-up charge suddenly discharges, causing a spark or a small shock.
So, static electricity is basically electric charge building up and waiting for a place to escape.r
