Lesson 2: Electricity Basics (Electricity, Waves & Info Transfer)
Vocabulary for Smithsonian STC-MS EWIT Unit
Terms in this set (25)
An instrument used to measure electric current in a circuit.
A device containing an electric cell or a series of electric cells storing energy that can be converted to electrical power.
A form of potential energy thatis stored in chemical bonds.
A continous conducting path for current.
An element or device in an electric circuit.
A scientific investigation in which one variable (the independent variable) is changed, and all others are controlled, or kept the same.
The net movement of electrons through a conductor. Often defined as the net amount of change passing through a conductor at a given point per unit time.
The variable in an experiment whose value is determined by the experiment.
A labeled drawing that explains or shows the parts of something. A diagram can be a type of model.
A form of kinetic energy that involves the transfer of change through an electrical conductor.
The presence or flow of electric charge.
A proposed explanation for an observation based on previous information that is used as a starting point for an experiment.
The variable in an experiment that the experimenter purposefully changes in order to determine its effect.
A statement that describes a cause-and-effect relationship in the universe and is based upon repeated experimental observations.
A tool scienctists and engineers use to represent ideas or provide an explanation. Models may include diagrams, drawings, physical replicas, mathematical representations, analogies, or computer simulations.
A circuit in which current flows in more than one closed path.
The rate at which energy is supplied or used.
To make an educated guess about the outcome of a situation.
A diagram that represents an electric circuit using symbols.
A circuit in which current flows only in one closed path.
A group of objects that function together as one unit; also, the set of related objects under study or consideration.
Any factor that could affect the results of an experiment.
Unit of electrical potential.
Essentially, a measure of the work associated with moving an electric charge from one point to another.
An instrument that measures electrical potential, or voltage, across a component or components in a circuit.
