Electrostatics Flashcards
1
Q
What is the definition of electrostatic?
A
- The study of the movement of charge i.e elctricity
2
Q
Conductors vs. insulators
A
- Conductors: allow charges to flow freely within them ( metals are excellent conductors)
- Insulator: do not allow charge to pass within them thus does not transmit electricity well. Non- metals are great insulators. In our body in the nervous system myelin makes great conductors.

Q
What is the electric field?
A
- it is the field that allows charges to move, it is a similar concept then the force of gravity on life. except the electric field is stronger.
- Just like any object has a force on gravity acting upon it, every electric charge has a force of electric field that surrounds it.
-
How to draw the lines:
- basics: comes out of + charges get into - charges
4
Q
What are capacitors?
A
- devices that help store charges
5
Q
What are uniform electric field lines?
A
they bend wheres as uniformed are parallel to
6
Q
Explain the concept of electrostatic energy?
A
- Energy is synanomous to work, and work is the the force needed to create a displacement
-
In the electrostatic field we look more so as potential energy the ability of charges to interact due to their position
- if they are farther apart ( larger radius) they will yield higher potential energy than if they were closer together, and means that they are less likely to come into contact.

Q
What is magnetisim?
A
- caused by a moving charge particle, that experiences a force due to it’s motion.
