Electrostatics and Coulombs stuff Flashcards
Static
Electrical charges at rest
Positive Charge
Objects having more positive net charges than negative
Negative Charge
Objects having more negative net charges than positive
Proton
Positive charged particle in nucleus of atom
Electron
Negative charged particle loosely held around atom
Coulomb
Unit of charge measurement amp seconds
Friction
Charge increase or decrease by moving contact
Conduction
Charge increase or decrease by contact
Induction
Charge increase or decrease by non-contact
Electrostatics
Basic law that states unlike charges attract & like repel
Power Formula
Current x volts

Coulombs Law
F = (k x q1 x q2)/r^2 - Used for finding force
