Electricity Flashcards
The result of electrons being pulled from one surface to another is called
static electricity
If you drag your feet across the carpet to create static electricity, what kind of charge do your feet become?
Negatively Charged
Static Electricity is the build up of….
charge

What is a current?
a continuous flow of electrons
What is current measured in?
Ampere (amps)
The pathway the current flows creates a …
circuit
What is a direct current?
Current that ALWAYS flows in one direction
Alternating Currents are?
currents that flow in one direction then switch and flow in the other direction
The power source for a circuit is called a
battery
What does DC stand for
Direct Current
What does AC stand for
Alternating current
How does a battery produce electricity?
By changing stored chemical energy into electrical energy
In order for electricity to be useful, we need a steady flow of it, known as a…?
current
In a battery, the electrons form from where?
The negative terminal of the battery
The path for electrons to move through must be a…?
Conductor
What is a conductor?
a material that allows electrons to move through it easily
Most metals are good or bad conductors?
good
What is an insulator?
a material that electrons have a hard time moving through
