Components in a Circuit
The energy source used in the circuits made in class.
What is a battery? *
The thing you change or test in an experiment.
What is a variable?
Something that reduces the number of contact points on a wire.
What is insulation?
Something that electromagnetic forces can do that gravity can not.
What is repel?
The component that controls the flow of electricity in a circuit.
What is a switch?
The standard model I compare my results to.
What is a control?
Two types of evidence that a circuit is complete and electrical energy is flowing through it. (100pts for each)
What is a light turning on or feeling heat?
A fundamental force of nature that acts between charged particles.
What is electromagnetic force?
The component that is the pathway for electric current.
What is a wire?
Limitations to my experiment such as time, cost, and access to materials.
What are constraints?
The component of an electromagnet circuit that does not have electricity running through it.
What is the core? *
Evidence we saw in class that there is a magnetic field present in an electromagnet circuit.
The part of a lightbulb that glows when energy is running through it.
What is a filament?
The number of variables I should change in an experiment at a given time.
What is one variable? *
The type of energy a battery holds which is changed into electrical energy when the circuit is complete? (Answer has two parts, 200pts for each part)
What is chemical potential energy?
The component of an electromagnet circuit that becomes a temporary magnet.
What is the core?
The two contact points on a lightbulb that allow it to light up and complete the circuit.
What is the bottom and side of the lightbulb?
The direction of the line on a graph of number of paper clips picked up vs number of winds of wire?
What is up (going from left to right)?
The Danish physicist that discovered electric currents create magnetic fields.
Who is Hans Christian Ørsted?
The effect of reversing the direction you wrap the wire around an electromagnet.
What is changing the direction of the poles?
