Coulomb's Law involves the force of static charges. In the equation F is calculated using two charges q1 and q2 in Coulombs, k is the Coulomb constant, also r is the distance between the two charges. In atoms, there electrons which are negatively charged, neutrons are neutral, and protons are positive. When there is an imbalance of electrons, it has a positive or negative charge. Occasionally electrons are exchanged between materials if and when they come into contact and separate, this would be called the triboelectric effect.

Circuits are closed and complete paths made of electrical components which allows a electric current to flow. There are two types of paths in a circuit: parallel and series. Series are when components are arranged within a line, there is only one path for the current to follow. Parallel is when there is split paths, allowing a current to flow in other ways. Most circuits have lot's of components in parallel and series.

Electric currents is a flow of an electric charge. Current is a measure of the amount and rate of that flow. Current is actually represented by the variable i and measured in Amps, and denoted by the letter A. It is related to resistance and voltage in the equation V=ir.

Resistance is the opposition to electric currents. Every material provides at least some resistance. The total resistance in series circuits is calculated by adding the resistance of all components. The total resistance in parallel circuits is calculated by taking the inverse of the sum of the inverses of the component's resistance. Resistance is shown as the variable r and measured in Ohms, which is represented by the Greek letter omega. One common component in lot's of circuits are potentiometers. Current is inversely proportional to resistance, so as the resistance went down, the current went up.

Voltage is an electromotive force, the potential energy change between the two points in a circuit. Voltage is shown as the variable V and measured in Volts, and is also denoted with a V. Ohm's law states that the voltage between any two points is equal to the current multiplied by the resistance: V=ir. In my circuit.

Power, in electricity, is the rates at which electrical energy will be consumed. It is measured in Joules per second, which is known as Watts (W). Power equals the voltage multiplied by a current. This equation could be manipulated to find different ways to calculate power.

Programming is the paragraphs of code that are written to create actions that the machine will run. These actions can go from measuring an instrument to literally walking depending on the machine. Also can be used to show images on screens and sounds that are sent through the speakers.

Electromagnetism happens because electric current makes a magnetic field, and also the opposite. A traditional electromagnet consists of insulated wire that is wrapped around a ferromagnetic core such as iron. When currents are run through the wires, the core becomes the magnet. Another example of electromagnetism are transformers. Transformers is a blockbuster movie that came out in the mid 2000's and is also a way of stepping down the voltage of an electric current.
