Term 2 electro magnetism Flashcards
Define static electricity
Static electricity is an imbalance of electric charges within or on the surface of a material
Define current electricity
Current is the flow of electrical charge or flow of charge carriers
Define electric charge
Electric charge is a basic property of matter. Charge can be positive or negative.
Define charge carriers
Charge carriers are charged particles that move through a conductor or through an electrolyte
Define negative charge
The type of electrical charge electrons have. Objects with more electrons than protons have a negative charge.
Positive charge
The type of electrical charge protons have. Objects with less electrons than protons have a positive charge.
Define conductor
A conductor is a material through which electric current is able to pass
Define insulator
An insulator is a material that does not allow charge to flow easily
Define ammeter
An ammeter is an instrument used to measure the current flowing through a section of the electric circuit
Define voltage
Voltage is the potential difference between two points of a component in an electric circuit
Define volt
The volt (V) is the unit of voltage/potential difference
Define voltmeter
A voltmeter is an instrument used to measure voltage/potential difference
Two types of electricity
Static electricity
When you brush your hair or when socks stick together in the dryer
Current electricity - when you switch on a lamp
The flow of an electrical charge - electrons moved through a conductor carrying the electricity
What does static mean
Static mans STILL or NOT MOVING
Law of attraction
Like charges repel
Unlike charges attract
