electrostatic generator
C2technical / academic
Definition
Meaning
A device that produces high-voltage static electricity through the mechanical separation of electric charges.
Any machine that generates a continuous supply of static electric charge, typically for scientific experiments, demonstrations, or industrial applications. Often synonymous with specific historical devices like the Van de Graaff generator or Wimshurst machine.
Linguistics
Semantic Notes
This is a compound noun where 'electrostatic' functions as an adjective modifying 'generator'. The term is highly specific to physics and engineering contexts.

Usage
Context Usage
Business
Extremely rare, only in highly specialised manufacturing or scientific equipment sales.
Academic
Common in physics, electrical engineering, and history of science texts, lectures, and lab reports.
Everyday
Virtually never used except in specific educational demonstrations (e.g., science museums).
Technical
The primary register. Used in specifications, research papers, and technical descriptions of charge generation and high-voltage phenomena.
Examples
By Part of Speech
verb
British English
- The apparatus was used to electrostatically generate a potential of 100,000 volts.
- They sought to electrostatically separate the particles.
American English
- We need to electrostatically generate a charge for the experiment.
- The process electrostatically isolates the components.
adverb
British English
- The charge was produced electrostatically, rather than chemically.
- The device functions electrostatically.
American English
- The machine works electrostatically, using a moving belt.
- It was generated electrostatically.
adjective
British English
- The electrostatic-generator principle dates back to the 17th century.
- An electrostatic-generator demonstration is scheduled.
American English
- The electrostatic generator principle is fascinating.
- He studied electrostatic generator design.
Examples
By CEFR Level
- The science museum has a large, round electrostatic generator that makes your hair stand up.
- An electrostatic generator, such as the Van de Graaff, creates high voltage by transporting charge on a moving belt.
- The Wimshurst machine, a type of electrostatic generator, employs two counter-rotating discs to induce and separate charge through influence.
Learning
Memory Aids
Mnemonic
Think of a generator that makes 'static' like when you rub a balloon on your hair, but on a massive, controlled scale. Electro (electric) + static (stationary charge) + generator (maker).
Conceptual Metaphor
A CHARGE PUMP (conceptualising it as a device that moves and separates charge to create pressure/voltage).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calquing of the compound order. The standard Russian term is 'электростатический генератор'.
- Do not confuse with 'электрогенератор' (electric generator), which is for current, not static charge.
Common Mistakes
- Misspelling as 'electro static generator' (should be one word: 'electrostatic').
- Confusing it with a general 'electric generator' (dynamo) that produces current.

FAQ
Frequently Asked Questions
No, it is the most famous type, but others include the Wimshurst machine, the electrophorus, and earlier devices like the Kelvin water dropper.
An electrostatic generator produces high-voltage, low-current static electricity (stationary charge). A normal power generator (dynamo) produces moving electric current (flow of charge) at usable voltages for power.
Yes, primarily in scientific research (e.g., particle accelerators), industrial applications like electrostatic painting or precipitation, and for educational demonstrations.
The high voltage induces charge on your body. Each hair becomes similarly charged, and like charges repel, causing the hairs to push away from each other and stand up.
