It is impossible to light a light bulb with static electricity. Although the electrostatic voltage is high, the discharge time is very short and it cannot be lit. Static electricity is only suddenly charged. Only when it is continuously charged and the charging voltage reaches the required voltage of the bulb can it be lit.

Static electricity is a kind of static charge or non-flowing charge (flowing charge forms current). Static electricity is formed when an object or surface accumulates charges, which are divided into positive and negative charges, that is, electrostatic phenomena are also divided into positive and negative charges.

Static electricity is not static electricity, but electricity that temporarily stays in a certain place macroscopically. When a person stands on a carpet or sofa, the human body voltage can be as high as 10000 volts, and the static electricity in the rubber and plastic film industry can be as high as 1000000 volts.

Causes of static electricity generation

1, contact over

When the electric balance between two substances is broken, many electrons are negatively charged and few electrons are positively charged. The higher the contact speed, the higher the electrostatic potential.

Step 2 rub

Friction is essentially a process of contact, so the static electricity generated by friction is the highest. The better the insulation of the material and the drier the environment, the more static electricity will be generated.

3. High energy radiation and high temperature

It is static electricity generated by electron overflow under extreme conditions.

4. Induction electrification

A non-conductive body close to a charged object will induce charges of opposite polarity at both ends.
