The unit of electric charge
Coulomb
Negatively charged particles surrounding the atomic nucleus
Electrons
A drawing using symbols to represent the different components of a circuit
Circuit Diagram
A combination of electrochemical cells connected togethe that produces a potential difference
Battery
Materials that allow electrons to move freely on and though them
Conductors
Two terminals in a cell or other electricity source; usually made of two different metals or a metal and another material
Electrodes
The continuous flow of charge in a complete circuit
Current Electricity
A electric charge that can be collected and held very nearly fixed in one place
Static Charge
These state that like charges repel, opposite charges attract, and neutral objects and charged objects attract each other
Laws of Static Charge
Devices that convert chemical energy into electrical energy.
Electrochemical Cells
Any device that transforms electrical energy into other forms of energy, such as a light bulb, buzzer, heater, or motor
Electric Load
Unit for measuring electric current
Ampere
Materials, such as glass, plastics, ceramics, and dry wood, that do not allow electrons to move easily on or through them
Insulators
The unit of potential difference
Volt
The amount of charge passing a point in a conductor every second
Electric Current
Positively charged particle in the atomic nucleus
Protons
Connecting a conductor so that electric charge flows into Earth’s surface
Grounding
Substance that conducts an electric current; in a dry cell, this is a moist paste; in a wet cell, this is a liquid.
Electrolyte
The ability to do work
Energy
The amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per coulomb of charge at another point in the circuit; also called voltage
Potential Difference
