Electrostatics, Capacitors, Batteries, and Resistors Flashcards
What is symbol for electric charge?
Q or q
What are the units for electric charge?
C (Coulombs)
What is the value for elementary charge, e?
1.6E^-19 C
What is the definition of elementary charge?
The amount of Coulomb’s associated with a proton or neutron
What is the value of a proton, an electron?
Proton: +e
Electron:-e
What is the value of Coulomb’s constant, K?
It is 9E^9
A coulomb is—– the same thing as e
NOT
How do you find the Electric force on an particle when it is acted on by 2+ objects?
You add up the net forces of the charges effects on the particle.
What is an electric field?
An electric field is a vector field created by source charged that permeates the space around them
How can we find the electric force of an electric field once the electric fired has been defined?
Use the equation
Force electric=q(E)
What are the two aspects that affect force?
Electric field strength and electric charge strength
What do the density of the field lines indicate?
How relatively strong the central change is.
Electric field is :
a vector?
a scalar?
vectors
What are the units for electric potential?
joule/coulomb
