Miscellaneous Materials Practical Application Variables Circuit Patterns

100

What is Ohm's Law
The formula that relates Voltage, Current, and Resistance

100

What is a Conductor
This material has free electrons which allows electricity to flow.

100

What is a Switch
This device opens and closes a circuit (turns it on and off)

100

What are Volts
This is the unit of Voltage

100

What is a Series Circuit
This type of circuit has only one path for electricity to flow

200

What is 8 Volts
This is how much voltage is needed to make 2 Amps flow through a resistance of 4 Ohms.

200

What is an Insulator
This material does not have any free electrons so electricity can't flow through it easily.

200

What is a Series Circuit
In this pattern if one light bulb burns out then they all turn off.

200

What are Amps
This is the unit of current.

200

What is a Parallel Circuit
This type of circuit has multiple paths for electricity to flow

300

What is 2 Amps
A voltage of 6 volts is applied to a resistance of 3 ohms and creates this current...

300

What is a Wire
These have no resistance and provide a path for electrons to flow.

300

What is a Parallel Circuit
In this pattern if one light bulb burns, the other lights stay on still.

300

What are Ohms
This is the unit of Resistance

300

What is an Open Circuit
This is when a circuit can't turn on because a path is not connected

400

What is 0.5 Ohms
A 2 volt battery will create a current of 4 amps when there is this much resistance.

400

What is a Light Bulb
This device turns electrical energy into both heat and light energy.

400

How do you increase brightness?
You can do this to your light bulbs by adding more batteries or by taking light bulbs away.

400

What is Energy (or electrical energy)
This is stored in the battery and a "dead battery" has run out of it.

400

What is a Closed Circuit
Any circuit where electricity can flow because there is at least one loop back to the battery.

500

What is the slope
If you make a graph of voltage vs current, Ohms law says the resistance is found from this part of the graph.

500

What is a Semi-conductor
Humans are an example of this kind of material. (Conductor, Insulator, Semi-conductor)

500

Fire extinguisher, Baking Soda, Fire blanket, Turn off electricity DO NOT EVER USE WATER!!!
These are things that can safely put out an electrical fire.

500

What is Power
This is the rate at which energy is used and is measured in Watts (W)

500

What is a Parallel Circuit
This type of circuit is how your house is wired. (Hint: When you turn one switch off, does everything else turn off too?)
