Electricity - 22/03/21 Flashcards
What is an Electron?
The substance which flows around a circuit, powering the components in it.
What is Static Electricity?
Electricity which has not yet been connected into a circuit and so has nowhere to move to, this builds up usually in kinetic energy sources.
What is a Van Der Graff Generator?
A type of generator/circuit which uses a belt to accumulate its electricity on a hollow metal globe.
What is a conductor?
A material which attracts or conducts electricity through itself, used to make circuits.
What is an insulator?
A material which does not conduct electricity and is used around currents so they are safe to use and touch.
What is a Switch?
A part of a circuit which can be used to divert or break up the circuit selectively to make it work differently.
What is a Motor?
A component in a circuit which powers other parts of the circuit by diverting energy to them.
What is an LED?
A type of electrically powered light.
What is an Electrical Circuit?
A closed shape made of conductive materials, designed to use electricity to power components like lights.
What is a Circuit Diagram?
Drawings which are used to represent a circuit which is going to be used in a design or project.
What is a Series Circuit?
A circuit which has only one primary path which all of the essential and main components run through.
What is a Parallel Circuit?
A circuit which has multiple paths, placed side by side like branches, where some of the main components are so that they can be operated and changed independently.
What is Current?
A measure of the flow of electrons around an electrical circuit.
What is an Amp?
The unit used to measure the current of a circuit, measured using an Ammeter.
What is Voltage?
The push by the battery provided to move the electrons around the circuit.
What are Volts?
The unit used to measure voltage, measured by a voltmeter.
What is an Electrolyte?
A solution which is used to conduct electricity to an object.
What is an Electrochemical Cell?
Another word for a battery, name comes from the chemical energy that batteries use.
What are Primary Batteries?
Batteries which can only be used once then are usually disposed of.
What are Secondary Batteries?
Batteries which can be used multiple times as they are rechargeable, very environmentally friendly.
