where do charges come from
What are the three ways in which an object can be charged?
charging by friction, charging by conduction, charging by induction
Who was the person that discovered and introduced the idea of positive and negative charges?
Benjamin Franklin
a battery has less and less capacity to recharge and power due to changes in what?
resistance
Can an electric vehicle be used by a current that flows in a single direction?
no
Agusta
What is the difference between conduction and induction
Conduction: contact if a charged object touches a neutral object, electrons can flow to the neutral object.
Induction: occurs when there is a temporary separation of charges in the neutral object.
If electric force is greater than gravity, why don't we typically feel the electrical force?
Positive electrostatic charges balance out negative charges meaning its neutral
As resistance increases, what happens to current?
decreases
an electric car charging station that can charge multiple vehicles at a time would most likely be what type of circuit?
parallel
What is the first fast-food chain to open an outlet in china?
KFC
Define law of conservation of charges
charge is neither created nor destroyed.
summarize coulombs law
The force between two charged objects is a) directly proportional to the quantity of each charge and b) inversely proportional to the square of the distance between them.
what will result in a faster charging time? a longer or a thicker charging cord?
thicker
what is the difference between a series circuit and a parallel circuit?
A series circuit has components connected in a line; the same current flows through each component. In a parallel circuit, components are connected so the current can flow through multiple paths at the same time.
What is the smallest country in the world?
Vatican City
Define seperation of charge
moving electrons from one object to another results in charged objects.
how would a wireless charger use electric fields to charge battery
the electric field increases the batterys volatge
Name 3 of the 4 things that increase resistance.
The length of a conductor increases, the cross-sectional area (diameter) of a wire decreases, The conductivity decreases, and the temperature increases.
How is resistance affected in a series circuit if identical resistors are added?
increase the total resistance because the resistance of each resistor simply adds up to the total resistance.
coprastastaphobia is the fear of what?
constipation
What principles determine how objects become charged?
An object becomes charged when the balance between electrons and protons is changed. The transfer of electrons determines charge.
What are field lines?
lines used to represent the direction and strength of the electric field
how does a battery move things like a vehicle or electric scooter?
Flowing electrons turn a magnet attached to the shaft
why are our houses wired in a parallel circuit?
it allows each appliance or light to operate independently, meaning if one device fails, the others continue to function
What's Bakkens parents name?
Rodney and Joanne
