Essential Vocabulary & Concepts
Picture Core Knowledge or Concept
Current
Electric current is the continuous flow of electrons (note: a spark is not continuous.)
The amount of charges per second is measured in amperes (amps or A).
circuit
An electric circuit is a closed (complete) path that allows current to flow.
An open circuit  (switch is open)  stops the flow of electrons.
Resistance at the Molecular Level A resistor or semiconductor is a material like silicon, germanium, or arsenic (used in computer chips) that lose or use electrical energy, slowing the flow.
device
A device is anything that uses or resists the flow of electrons. Devices include resistors, buzzers, and light bulbs.
They are  represented as resistors in a circuit.
conductor
Conductors are materials that allow electrons (red) to flow like metal wires. A conductor transfers electric charge well, but electric charges do not flow easily through every material.
battery
Source:
Charges in an electric circuit flow because of a difference in electrical potential energy called voltage, measured in volts (V).
You can think of voltage as the amount of force pushing an electric current. A voltage source is a device that creates a potential difference in an electric circuit.
Resistance
Resistance is the measure of how difficult it is for charges to flow through a material. The greater the resistance, the less current there is for a given voltage. The unit of measure of resistance is the ohm (Ω). Resistance can vary with:
  • The material from which the wire is made.
  • Length: Longer wires have more resistance.
  • Diameter: Thinner wires have more resistance
  • Temperature: Higher temp, more resistance.
Ohms
FormulasThe relationship between resistance, voltage, and current is summed up in Ohm’s law. Ohm’s law says that the resistance (R) is equal to the voltage (V) divided by the current (I).
series
If all parts of an electric circuit are connected one after another along one path, the circuit is called a series circuit. In a series circuit, there is only one path for the current to take. Because of this, if one light goes out in a series circuit, the other lights will go out. Adding lights to a series circuit will make other lights in the circuit dimmer.
Parallel
In a parallel circuit, there are several paths (called branches) for current to take. If one light goes out in a parallel circuit, the other lights in the circuit will remain lit because there is still current in the other branches. When branches are added to a parallel circuit, the overall resistance actually decreases because the current has more paths to follow.
multimeter
A multimeter includes each of these functions.   
Circuit Symbols
A circuit diagram shows the sources, conductors, and devices (as resistors) using symbols
Bob & Paul
Scientist
 
Paul and Joseph Galvin, founders of Schaumburg Illinois based Motorola along with son Paul, developed the car radio and the germanium based transistor in 1955.

Technology

The Transistor (1955) was the first mass-produced semiconductor, the forerunner of today's microprocessors at the heart of telephones, TVs, and almost all electronic devices. Transistors allowed early miniaturization of low-power electronics.
The older vacuum tubes used to break,burn out, use alot of electricity, and alot of space.
