fundamental physical quantity responsible for electrical phenomena
Charge
Unit is Coulomb (C)
charge of a proton
1.6 × 10−19 C
charge of an electron
−1.6 × 10−19 C
three ways of charging an object.
- Rubbing
- Conduction
- Induction
Sum of all positive and negative charges in the object
net charge
helps determine which material combination create the most static electricity
triboelectric series
If a system starts with equal charge distributions, it will be in equilibrium unless a charge is added or removed
Law of conservation of charge
Electric force is determined by the product of two charge values divided by the square of the distance between the charges
Coulomb’s law
Field existing in a region around a charged particle
electric field
Field existing in a region around a charged particle
Gauss’ law
A hypothetical surface immersed in an electric field that may or may not enclose a charge
Gaussian surface
Strength of an electric field over an area in a field region
electric flux
What is Coulomb’s Constant (k)?
9 × 10^9 N·m²/C²
