MEGA COLLECTION 4

Electrical Engineering is concerned with the study and application of electricity, electronics and electromagnetism, dealing with the large-scale electrical systems such as power generation transmission, controlled distribution and utilization. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications.

Electrical engineering may include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to process information. More recently, the distinction has become blurred by the growth of power electronics.

Electrical Engineering as a Subject:

Electrical engineering is one of the core fields of engineering, so it is always evergreen in terms of Scope and Job Prospects. Electrical Engineering is the heart of whole engineering discipline and therefore it scope will never fade even many years from now. Nowadays, we see Electronics playing an important role in the implementation and control of Electrical Machines. Keeping this fact file in mind the course have transformed from core electrical Engineering into a Fusion of Electronics and Electrical and has been renamed as Electronics and Electrical engineering or simply EEE.

Career Scope an Placement Prospects:

Electrical Engineers are needed in all manufacturing units, All major companies of public and private sector such as Electricity Boards, Large Scale Industries, Manufacturing Plants, Power Corporations, Hydro-Electricity sector are continuously in need of Electrical Engineers for their projects. Electrical Engineers also find job prospects in Design Industries, Production plants, Natural gas plants, Petroleum as well as in steel and chemical plants. Many premier Educational and Research Institutions regularly intake electrical engineers as graduate Engineer trainees and Management Trainees to work on research projects.

Electrical Engineers can also get a job in Major players in Public Sector such as Pakistan Railways, Armed forces(Technical Branch) and also in Thermal and Nuclear power Corporation Limited.

What is this job like?

Electrical engineers design new and better electronics. They also test equipment and solve problems. A project starts by deciding what the new electronics will do. Then, the engineer designs the circuits and other parts of the electronics. Engineers might draw their designs using a computer.

Later, the engineers test their designs and make them better. Many projects don't work at first. The engineers have to figure out why and then fix them.

Electrical engineers work on many kinds of products. They might work on cars, robots, cell phone systems, the lighting and wiring in buildings, and radar and navigation systems.

Some examples of high-tech projects that electrical and electronics engineers work on are global positioning systems that can pinpoint a car's location, giant generators that can power entire cities, or a new design for an airplane's electrical system.

Engineers work in offices, labs, or industrial plants. Many work a normal 40-hour week. At times, they work longer to meet deadlines.

INPUT DEVICES

13:12

Unknown

An input device is any hardware device that sends data to the computer, without any input devices, a computer would only be a display device and not allow users to interact with it, much like a TV. In the picture to the right, is a Logitech trackballmouse and an example of an input device. Below is a complete listing of all the different computer input devices that can be used on a computer.

Types of input devices

Audio conversion device
Barcode reader
Business Card Reader
Digital camera and Digital Camcorder
Finger (with touchscreen)
Fingerprint scanner
Gamepad, Joystick, Paddle, Steering wheel, and Microsoft Kinect
Graphics tablet
Keyboard
Light gun and light pen scanner
Magnetic-stripe reader
Medical imaging devices (e.g., X-Ray, CAT Scan, and Ultrasound images)
Microphone (using speech recognition)
MIDI keyboard
MICR
Mouse, touchpad, or other pointing device
Optical Mark Reader (OMR)
Punch card reader
Remote
Scanner
Sonar imaging devices
Touch screen
Video capture device
VR helmet and gloves
Webcam

Tip: Keep in mind that drives such as a CD-ROM, DVD, and aFloppy diskette drive may be capable of sending the computer information, but they are not input devices. These devices are considered storage devices.
