Electrical and Electronic: many people asked about the different between these two. This may be about power and system.

Electrical Engineers

As an electrical engineer, your job is to research and develop ways of transmitting electrical power through mechanical objects and finding ways of storing the energy, as well. You also work with electrical signals. While cell phones may be developed through electronic engineering, the voice and the visual and text data are sent through electrical signals. The satellites that transmit a signal to another phone is another example of electrical engineering at work. On a larger scale, some of the areas in which electrical engineers work include:

• Electromagnetics
• Optics (lasers)
• Power efficiency
• Motors
• Lighting
• Utility-power transmission
• 

Electronics Engineering

If you work in electronics engineering, you focus on both electronics engineering and computer engineering. College-degree programs may merge these two areas into a single field. The difference between the two areas is that computer engineers only work with computers and computer-related devices. Here are some items that are common to the electronics engineering profession:

• Portable music devices
• Global positioning devices
• Broadcasting systems
• Telecommunication devices and systems
• Analog circuitry
