Electricity Flashcards
What Are Electrolytes?
a liquid or paste that contains ions
what are Electrodes?
2 metal sticks or prongs stuck into electrolytes-they interact with the ions+charge the circutry
What is a Resistor?
a material That can slow electrical current
what is a electrochemical cell?
a package of chemicals that converts chemical energy into electrical energy that ius stored in charged particles
what is DC?
(direct current) is the back and forth flow of electric current at regular intervals called cycles
what is AC?
(alternanting current) is the back and forth flow of electric current at regular intervals called cycles.
what is a load?
a device that converts electrical energy into another form of energy
define Volt
the SI unit for measuring voltage
define Ohms
The SI unit for measuring resistance
what is a superconductor?
a type of conductor that has no electrical resistance below a characteristic tempurature
What is a Ampere?
The SI unit for measuring amps
what is a circut diagram?
A circuit diagram is a graphical representation of an electrical circuit
What is a Transistor?
is used in circuits to either amplify or switch electrical signals or power
What is a Secondary cell?
A rechargeable electric cell that converts chemical energy into electrical energy by a reversible chemical reaction. Also called storage cell.
what is a Dry Cell/ primary Cell?
an electric cell that produces current by an irreversible chemical reaction.
