What is a resistor/lightbulb?

200
This type of circuit has three bulbs that are all very dim.
What is a series circuit?
200
The definition of current.
What is the flow of electricity?
200

Describe how voltage works.

It is a push that moves electrons through a circuit.

200
In a series circuit when you add more lightbulbs, this happens to the total resistance.
What is increases?
300

Type of material used for wires that allow electrons to flow.

What is a conductor?

300
In this type of circuit, each bulb has its own pathway to the battery.
What is a parallel circuit?
300
The formula for calculating current.
What is I = V/R?
300
As voltage increases, this happens to the current in a circuit.
What is increases.
300

In a parallel circuit, when you add more branches, this happens to the total resistance in the battery.

What is decreases?

400

Tool used to measure voltage.

What is a voltmeter?

400
It doesn't matter where you measure current in this type of circuit.
What is a series circuit?
400
