2. Indicator Statement: Analyze the functioning and applications of electrical systems. Objective(s): Explain science and mathematical concepts applied in electrical technology. Such as: Resistance Current (AC & DC) Voltage Circuits Magnetism Ohm’s Law Ratio Identify and describe how various types of electric circuits (i.e. series and parallel) provide a means of transferring and using electrical energy to produce heat, light, sound, as well as chemical changes. Solve for the unknown in a linear equation related to electrical technology. Long Reach High School - Foundations of Technology - Mr. Ash1/2/2013

3. Electricity is a natural force of nature. It is a general term for the presence and flow of electrons making an electric charge. Over the past 100 years people have harnessed this force and integrated it into a variety of electronic devices that have become the backbone of our society.

4. The technology of producing, storing, controlling, transmitting and getting work from electrical energy. The technology of using small amounts of electricity for controlling, detecting, collecting, storing, retrieving and processing information Generator, Motor, Electric Heater, etc. Thermostat, Computer, Cell Phone, Digital Watch, etc. Long Reach High School - Foundations of Technology - Mr. Ash1/2/2013

5. An Electronic Circuit consist of a path for electrons to flow from an energy source. The Amount of Electron Flow depends on the resistance in the circuit. More Resistance = Less Flow. If there are no components in a circuit except a battery it causes a short circuit which drains the charge quickly. Long Reach High School - Foundations of Technology - Mr. Ash1/2/2013

7. Ohm suggested that if you double the Voltage across something that provides resistance, then the current would double. V = I R x I = VRVR R = VIVI Long Reach High School - Foundations of Technology - Mr. Ash1/2/2013

8. Each component has the same current. If two components are identical voltage is divided equally. There are two ways of connecting components: Each component has the same voltage. Both components have full voltage. Long Reach High School - Foundations of Technology - Mr. Ash1/2/2013
