Unit 2 Energy
The Big Idea: Electricity is the flow of electrons.
Before you begin, download the unit 3 content assignment checklist. This is a chronological list of the content assignments that you must complete. Remember all notes, questions, reflections and worksheets are to be kept in your journal.
3.1 Circuits
The Content:
 circuits must be complete for electrons to flow
 basic components include: battery, load, resistor, switch
 types of circuits include: series, parallel, short circuit
 current flow in a circuit: alternating circuit (AC) and direct current (DC)

Practical ElectricityIMPORTANT! Technically electrons flow through circuits from the negative side of a battery to the positive side of a battery. HOWEVER, conventional current is assumed to flow from the positive end to the negative end. The discretion was caused during the discovery of electricity by Benjamin Franklin. By the time the mistake was discovered conventional current flow was well established, even though technically the flow is from negative to positive. Read more about this on allaboutcurrents.com.
