WHAT IS ELECTRICITY?
Electricity is the movement of electrons. Electrons create charge, which we can harness to do work. Your lightbulb, your stereo, your phone, etc., are all harnessing the movement of the electrons in order to do work. They all operate using the same basic power source: the movement of electrons. There are 3 basic principles in electricity:
V = I * R

Your lightbulb, your stereo, your phone, etc., are all harnessing the movement of the electrons in order to do work. They all operate using the same basic power source: the movement of electrons. There are 3 basic principles in electricity:
- Voltage is the difference in charge between two points in volts = V
- Current is the rate at which charge is flowing = I
- Resistance is a material’s tendency to resist the flow of charge (current) = R
V = I * R
WHAT IS STATIC ELECTRICITY?
Static electricity occurs when there is an imbalance of positively and negatively charged atoms in or on an object. When something is static, it is not moving. The charges that create static electricity do not move away from the object they are stuck to it. Therefore, the object remains charged. For example, your clothes are charged by friction as they rub against each other inside a dryer. Positive charges build up on some clothes, and negative charges build up on other clothe. Because clothing is an insulator, the charges stay on each pierce of clothing, creating static electricity. Lightening is also an example of static electricity.
WHAT IS CURRENT ELECTRICITY?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current electricity the electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions. Power plants produce AC electric current. Alternating current (AC) is the type of electricity that power companies provide for us to use in our homes.
Series and Parallel Circuits
Series Circuits: A series circuit is a circuit in which all parts are connected in a single loop. The charges traveling through a series circuit must flow through each part and can only follow one path.
Parallel Circuits: A parallel Circuit is a circuit in which different loads are located on separate branches. Because there are separate branches, the charges travel through more than one path. Which has more current parallel or series circuit? The formula for current is I=V/R. High current =high thermal energy= high fire risk
