New cards
Conductor
A material that allows electrons to pass freely from atom to atom. Metals are examples of this.
2
New cards
Insulator
A material that does not allow electrons to pass freely through it. Examples are glass, wood, plastic, and rubber.
3
New cards
Circuit
A complete pathway for charges to flow
4
New cards
Series
A circuit with only one path for electrons to take.
5
New cards
Parallel
A circuit with multiple paths for electrons to take.
6
New cards
Opposition
When two negative or two positive terminals of a battery are touching. Batteries cancel each other out. No electrons flow from batteries.
7
New cards
Short Circuit
An unwanted, low resistance connection between two points in a circuit where nothing is being powered. Results in excess heat being released.
8
New cards
Current Electricity
Electricity that is able to flow continuously.
9
New cards
Resistance
How hard it is for the electrons to flow through the circuit.
10
New cards
Amperage
The number of electrons flowing past a given point in a second.
11
New cards
Voltage
The amount of force pushing an electric current.
12
New cards
Path of Least Resistance
When there are multiple paths for electrons to take they will flow on the easiest path.
13
New cards
Cell
A battery
