Vocabulary
Conductor
A material that is good at conducting electricity, electrons can travel freely through materials.
Two positively charged objects will:
Repel
Parallel Circuit
Electric Current has multiple paths to follow
What is Voltage?
Pressure from a power source in electric current that pushes charged electrons through wires of a circuit.
What is a load?
Anything in a circuit that uses electricity
Insulator
A material that is bad at conducting electricity, electrons cannot travel through the material with ease
Two negatively charged objects will:
Repel
Series Circuit
Electric current has one path to follow
What is Current?
The flow of Electrons through a circuit
Static Electricity
Two objects are rubbed together, and friction between the objects causes electrons to move from one object to the other.
Semi-Conductor
A material that can conduct electricity under certain circumstances.
One positive charged object and one negative charged object will:
Attract
What happens if one load from a parallel circuit breaks?
The electric current will follow different paths.
What is Resistance?
How much an object resists passage of an electric current
What happens when a Circuit is open?
Current cannot flow
Electric Motor
A device that uses electromagnetic induction to convert Electrical energy to Mechanical energy.
What happens if a Series circuit breaks?
The electric current will have no more paths to flow through and will stop conducting electricity.
What is Electromagnetic induction?
Process of using magnetic fields to produce a voltage, and in a closed circuit, a current.
What happens when a circuit is closed?
Current can flow
Electric Generator
A device that uses electromagnetic induction to convert Mechanical energy to Electrical energy
In circuits, electricity flows from what charge to what charge?
negative to positive
What happens to the strength of an electromagnet as you increase the number of coils?
The electromagnet will increase in strenghth.
