Electricty And Magnets Flashcards
Define conduction
The proccess by which electricity is directly transmitted
Define insulator
A material that does not allow electricty to flow
How does an object become charged
When a negative charge is rubbed against a positive charge
Define a magnet
A material that has its component atoms ordered that the material exhibits properties of magnetism
List 3 facts about parallel circuits
They have multiple paths, they keep light bulbs on even if 1 goes off, and they require extra wire to complete the circuit
What type of current comes from the outlets in your home
Ac currents
Define magnetic field
An area around a magnetic material
What is the ohms law formulas and what is each measured in
V- volts. I-amps. R-ohms
List three facts about a series circuit
1 path. All light bulbs go out if one breaks
Define induction
The process by which a body having electric properties produces magnetism without contact
Define magnetic pole
The two end points of a magnet that attract and repel eachother
What is the formula for power
Volts times current
Define magnetic domain
Billions of atoms that all have magntic fields and are lined in the same way
Define conductor
Material that allows electricity to flow
How can you increase the strength of an electromagnet
Add more batteries
Define electroscope
An instrument for detecting and mesuring electricity
Define electric current
A flow of electric charges
Define solenoid
A cylinder coil of wire acting as a magnet
Define static electricity
The build up of charges on an object
Define electric circuit
A path in which electrons from a voltage or current flow
