Electric (electron) movement
Current flow is affected by__________ of an object (length, width, temperature, material)
What are properties
The behavior of two oppositely charged objects
What is attract?
What is the thing that closes and opens the current in a circuit.
What is a switch.
These prevent circuits from overheating and starting a fire in homes
What is a circuit breaker or a fuse
The behavior of 2 like charged objects
What is repel
this is a path in which electric charges can flow.
What is an circuit.
This is the unit of electric current.
What is A for Ampere
Electric Current move easily in these.
What are conductors
When the positive and negative charges no longer balance. This is when negative charges are built up much more than positive.
What is static electricity?
Objects become charged by touching
What is conduction or friction
Name things (2) that electrons flow easily through. Examples
What is conductors, wide wires, cool wire or short wires
Batteries and power plants are examples of this
What is an energy source
Transfer of electrons between objects in contact
What is charging by contact
An electric charge in continuous motion.
What is an electric current?
Happens when a wire is very long
What is high resistance
Name at least 2 materials that could slow the flow of electrons in a circuit.
What is wood or plastic or rubber
In this circuit, devices are connected so there is only 1 closed path for current to follow.
What is series
A train that uses electricity and magnetism to travel
What is Maglev
Electric currents are surrounded by these....
What is an electric fields
Objects become charged without touching
What is induction or polarization
This subatomic particle flows easily in a circuit.
What is electron
This is a measure of the amount of electrical potential energy transferred by an electric charge as it moves from one point to another in a circuit.
What is voltage
