Chapters 14-17 Flashcards
Open Circuit
A circuit where one part of the circuit has broken away or been detached so energy cannot flow throughout the circuit
Closed Circuit
A circuit that is whole and energy can flow thought all the circuit
Short Circuit
A circuit with very low resistance so very little energy actually goes into the object
Potiental Difference
Electric Currents need a difference in electric energy to flow
Voltage
The poteintal difference between two points
Current
The flow of electrical charge carriers throughout a conductors
Insulator
An Insulator is a material that does NOT
allow charges to move about easily
Insulator
An Insulator is a material that does NOT
allow charges to move about easily
Resistance
The ratio of the voltage
across a device to the current through it.
Series Circuit
Resistors wired in a chain so the energy only has one path to go. Current is the same throughout the circuits
Parallel Circuit
Resistors wired in two or more paths. The voltage is consistent throughout the circuit
Electric Field
A region around a charged particle or object within which a force would be exerted on other charged particles or objects
What is an electric current?
A path where electrons travel from a source or battery to a end point
What is an electric charge?
The physical property that causes an object to experience a force in a magnetic field. Caused by loosing or gaining an electron
How does a battery work?
Chemical reactions occur in the battery and create a electrical difference. Then the only way to get to the positive side of the battery is to go through the conductor since the electrolyte blocks it
What is static electricity
A stationary electric charge
What does it mean for an object to be charged?
The protons and electrons of that atom aren’t even
What is Coulomb’s law?
The interaction between objects is a non contact interaction and acts over a certain distance
What is a Electric Field?
The electric force per unit around an object
How is the strength of an Electric Field determined?
How close the field lines are
Through point charge
Also through Coulombs Law
How is energy transferred in a circuit?
It goes from the chemical energy in the battery to the electric energy in the circuit.
