(13 cards)
What is an electron
a stable subatomic particle with a charge of negative electricity
What is an electric current?
the flow of electric charge through a conductor, measured in amperes (A)
What is resistance?
the opposition to the flow of electric currents measure in ohms.
How do you distinguish between series and parallel circuits?
series circuits have one path for the current parallel circuits have multiple paths.
What is a conductor
a material that allows electric current to flow through it
examples of a conductor
copper, aluminium
Insulator
A material that resists the flow of electric current
Examples of insulator
rubber, plastic
What is electric current measured in
Amps
What is an ammeter used for
Measure electric current
Two types of circuits
- Series
- Parallel
Voltage
the pressure from a power source thst pushes charged electrons.
