What is Electric engineering: Definition and 11 Discussions

Electrical engineering is an engineering discipline concerned with the study, design and application of equipment, devices and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution and use.
Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics, and electrical materials science.Electrical engineers typically hold a degree in electrical engineering or electronic engineering. Practising engineers may have professional certification and be members of a professional body or an international standards organization. These include the International Electrotechnical Commission (IEC), the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET) (formerly the IEE).
Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from circuit theory to the management skills of a project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to sophisticated design and manufacturing software.

    Big doubt about graphene in batteries

    Well people i'm looking electric Motorcycles. And the same seller it's selling a 72V50Ah battery and a 72V60Ah battery, both IN THE SAME WEIGHT, every battery in the shop occurs the same. So or we have a factory mistake, scam, witchery .....or...graphene in the lithium. I have been reading that...

    Opamp Voltages: Finding Output Voltage with Inverting and Non-Inverting Amps

    Homework Statement There are unknown values for input voltage, but we know it is sinusoidal. There is an inverting amp connected in parallel with a non inverting amp. The goal is to find the output voltage. I have three questions. 1: if the problem states that "power rails for both opamps are...

    Finding resistance, electric engineering problem

    Homework Statement Hi there. I have to solve this problem, and I'm having some doubts. It is desired to build an electric engine of 0.9[HP], which will be connected to 220[V]. This will be done by a Cu wire with a cross section of 1.2 [mm²]. Supposing an efficency of 90% compute how long...

    Need help with setting up a light system for a float for my old elementary school.

    Hey physics forums! I was asked by my elementary school to help set up a system to make lights flash with the beat of music on a parade float. I'm a nuke engineer student at purdue but I think this is within my grasp. If It is too expensive or too much to make Christmas light flash with the beat...

    A question in my electric engineering class

    [img=http://img214.imageshack.us/img214/9254/untitledqqag4.th.jpg] it's a question given in the sample exam I think for the first question, there is not much we can do to recover the function x(t), because it gets squared ... for the second part, sampling rate needs to be greater than 2*wm...
