Circuits
The flow of electrons
What is the electric current?
These are materials through which an electric current can pass.
What are conductors?
In this type of circuit, electricity has only one path to follow.
What is a series circuit?
Which particles found atoms have the property of negative charge?
electrons
When a current flows in a wire, the number of electrons in the wire ______________ change.
A. does
B. does not
This is the pathway taken by an electric current.
What is a circuit?
These are examples of conductors.
aluminum foil, copper, iron (metals)
In this type of circuit, electricity has more than one path to follow.
What is a parallel circuit?
Explain what happens when you rub a balloon on your head and then stick it to the whiteboard.
The balloon picks up electrons from your hair giving it a negative charge and then attracts to the positive charge of the whiteboard
The measurement of an electric current
What is resistance?
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
What is a closed circuit?
These are materials through which an electric current CANNOT pass.
What are insulators?
This is a material that cuts down the flow of current, but does not stop it.
What is a resistor?
How do positively and negatively charged particles interact?
What is attract?
In what part of the circuit is energy transferred in?
A. What is the load (power source)
This type of circuit is an incomplete circuit where there is some part that is not connected and electricity cannot flow through it.
What is an open circuit?
These are some examples of insulators.
sand, rubber, wood, plastic
These are the basic materials needed to make a complete circuit.
What are a power source (battery or outlet), wires, and a light bulb?
Providing a path for electric charges to flow safely into the ground is called ____________________.
What is grounding
If the current is broken or open, what happens to the electrons and the light bulb?
the electrons stop flowing and the light stop glowing.
This is a device that is used to open and close a circuit easily without connecting and disconnecting the wires.
What is a switch?
Name the type as a conductor or insulator:
A Lemon
conductor
This person invented the light bulb.
Who is Thomas Edison?
What are three ways by which objects can become electrically charged?
What is Contact, Induction, and conduction
The function of a battery in a circuit is to ______________________.
To push the electrons through the wires.
