Current from static electricity

In summary, static electricity is a build-up of electric charge on the surface of an object, caused by an imbalance of positive and negative charges. It is created when certain materials are rubbed together and can be converted into current electricity through electrostatic induction. While it is mostly harmless, it can be dangerous in certain situations and proper discharge is important to avoid hazards. The main difference between static electricity and current electricity is that static electricity is stationary and involves an imbalance of charges, while current electricity is constantly flowing through a conductor.

If I rub my socks around on the carpet, then touch the end of my unplugged laptop charger, and get a spark, why doesn't the breaker pop?

The current flows only for a tiny fraction of a second. That's way too short a time.

and its really low current, maybe ~ a few 10's of mA - way below the fusing current rating of that fuse

Are you actually trying to damage your laptop charger ! If not then best stop now.
 

What is static electricity?

Static electricity is a build-up of electric charge on the surface of an object. It occurs when there is an imbalance of positive and negative charges, and the charges are not able to flow or discharge.

How is static electricity created?

Static electricity is created when certain materials, such as rubber and plastic, are rubbed together. This rubbing causes the transfer of electrons between the materials, resulting in an imbalance of electric charge.

What is the difference between static electricity and current electricity?

The main difference between static electricity and current electricity is that static electricity is stationary, while current electricity is constantly flowing. Static electricity also involves an imbalance of charges on the surface of an object, while current electricity involves a continuous flow of electrons through a conductor.

How is current electricity created from static electricity?

Current electricity can be created from static electricity through a process called electrostatic induction. This involves bringing a charged object close to a conductor, which causes the charges to separate and create a flow of electrons through the conductor.

Can static electricity be harmful?

In most cases, static electricity is harmless. However, in certain situations, such as in the presence of flammable gases or liquids, it can be dangerous. It can also cause damage to sensitive electronic equipment. It is important to discharge built-up static electricity properly to avoid potential hazards.
