Study Notes

Electroscopes and Charging Bodies

The gold-leaf electroscope measures the presence and magnitude of electric charge on an object.
Material bodies are normally electrically neutral, meaning they have an equal number of positive and negative charges.

Charging Bodies

A body becomes negatively charged when it gains electrons, causing the gold leaves in the electroscope to diverge (move away from each other).
A body becomes positively charged when it loses electrons, also causing the gold leaves to diverge.
To electrify a neutral body, it is essential to bring it into contact with another body that has a surplus or deficiency of electrons.
