Electric Charge Flashcards
1
Q
elementary charge
A
e= 1.6 x 10^-19 C
2
Q
Coulomb’s Law
A
3
Q
Superposition of Forces
A
Vector sum of force from each individual charge
(Make sure to add tip to tail)
4
Q
Electric Force
A
5
Q
Electric Field from a Point Charge
A
6
Q
Capacitors (Dielectric)
A
7
Q
Charge on a Capacitor
A
Q=CV
For a given voltage, a larger C means greater stored charge
8
Q
Energy Stored by a Capacitor
A
9
Q
Ohm’s Law
A
V=IR
Resistance is how much an object opposes flow of charge through it
Resistance is proportional to length/area
