Circuits
The rate at which electrons flow past a point in a complete electrical circuit; SI unit of ampere
What is a current?
The study of stationary electric charges or fields as opposed to electric currents
What is Electrostatics?
Like charges repel, and unlike charges attract
What is The Law of Charges
doesn’t let electrons move around within the material freely
What are insulators?
Kcq1q2/r2
What is the electricstatic force equation?
All of the current flows through each part of the circuit
What is a series circuit?
electric force per unit charge; radially outward from a positive charge and radially in toward a negative point charge
What is an electric field?
The force of attraction or repulsion between two charged bodies is directly proportional to the distance between them
What is Coulmobs law
lets electrons move around within the material freely
What are conductors?
9 X 109 N*m2/C2
What is the constant of the electrostatic equation?
There are two or more paths for the electricity to flow the current is divided into separate paths
What is a parallel circuit?
A charge of electricity generated by friction
What is triboelectricity
The principle that electrons are neither created nor destroyed but simply transferred from one material to another
What is Law of Conservation of Charge
aluminum
What is a conductor?
E=kq/d2
What is the electric field strength equation?
When work is done on a positive test charge by an external force to move it from one location to another, electric potential ___
What is electric potential increases?
A list that ranks materials according to their tendency to gain or lose electron
What is triboelectric series?
V=IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current
What is Ohm’s Law
sea water
What is a conductor?
Req=R1+R2
What is the series circuit equation?
The force which makes a current continuously flows through a conductor
What is electromotive force?
The process of removing the excess charge in an object by means of the transfer of electrons between in and another object of substantial size
The magnitude at which electrostatic charges repel or attract is directly proportionate to the magnitude of charges when multiplied
What is Law of Attraction
dry air
What is an insulator?
1/Reg=1/R1+1/R2
