Electric Forces
The force between charged particles
electric force?
current flows through past known as.
Circuits
wooden spoon
insulator
This device measure electric current, even in small amounts
What is a galvanometer?
Neutrons are _____
Neutral
Electrons has a ___ charge
negative
what is the continuous flow of charge?
Electric current
gold
conductor
In this device, electricity is supplied, causing a magnetic field that causes motion
What is a motor?
Protons are ____
Positive
if electrons cannot move freely, so this cannot carry a current
insulator
True or false:
Does current flow in a loop
rubber
insulator
This device is the opposite of a motor, and uses mechanical energy to create electricity
What is a generator?
true or false:
negative and negative attract to each other
False
Electric field lines point in the direction that a force would push a ___ charge
Positive
What charges flow through a circuit?
Electrons
name 3 conductors
any medal named
What happens When opposite charges move closer together
the potential energy increases
True or false:
Lighting bulbs are made up of moving electrons
True
True or false: there are electric charges, forces, and fields in your body
True
acts like a force that causes currents to flow?
Voltage
why can’t electricity flow through insulators
Electrons are tightly bound to atoms, making them difficult to move
What is the buildup of charge on an object?
Static electricity
If an object gain electrons, it will have an overall ___ charge
Negative
