# Summary
|
|
* Net charge changes only when charge travels in and out of a system.
|
|
* Charging usually happens through electron transfer.
|
|
* Induced charge separation polarizes an object without contact. Happens in neutral conductors and insulators.
|
|
* In conservation problems, charge of separated objects should sum to charge of system.
|
|
* Grounding occurs when a system connects to a large neutral object.
|
|
* Conductors let electrons move easily, insulators only let bound charges shift slightly.
|
|
* Main 3 ways to charge: friction induction contact. |
