Study Notes
Static Electricity
- Static electricity occurs when atoms gain or lose electrons, becoming positively or negatively charged.
- Gaining electrons results in a negative charge, losing electrons results in a positive charge.
- Conductors allow electrons to move easily; insulators do not.
- Opposite charges attract, and like charges repel.
- Charged objects attract neutral objects.
Charging by Friction
- Rubbing two neutral objects together transfers electrons, creating charged surfaces of opposite polarity (one positive, one negative).
- The electrostatic series shows which materials are more likely to become positive or negative when rubbed together.
Charging by Conduction
- Contact between a charged object and a neutral object transfers charge, resulting in both objects having the same charge as the original charged object.
Charging by Induction
- Bringing a charged object close to, but not touching, a neutral object rearranges charges in the neutral object, creating a separation of positive and negative charges.
- No direct electron transfer occurs (touching is required for conduction).
Electric Discharge
- Rapid transfer of charge between objects, often visible as sparks.
Grounding
- Connecting an object to the Earth to allow excess electrons to flow away, neutralizing the object.
Lightning
- Ice crystals in storm clouds rub together, creating static charges.
- Negative charges accumulate at the bottom of the cloud, and positive charges at the top.
- The large potential difference between the cloud and the ground leads to a discharge (lightning).
- Negative charges in the cloud are attracted to the positively charged ground causing lightning to strike.
