What is an electric current?
The flow of electricity through a conductor.
How does a circuit form? What does the path of a circuit usually consist of?
An electrical circuit is formed when an electric current passes through an unbroken path of conductors, typically consisting of wires.
What is a voltage source? Give an example of one.
Voltage sources, such as batteries, increase the volts of electrons in an electrical circuit and move the current along the path.
What is the job of the switch in a path?
To open or close the path of the electrical circuit.
When do the electrons in a circuit move? How about protons?
When voltage is applied to an open circuit; protons are not free to move.
What stops electricity in a circuit from flowing in the same direction the whole time?
Resistors.
What happens to electrons when they move through a resistor?
They lose energy and can be transformed into light and/or heat.
What are the two types of electrical circuits?
Parallel and series.
What's the difference between parallel and series electrical circuits?
Series: one path; parallel: more than one path.
How does energy change form in a flashlight?
From potential/electrical to heat/light.
