Er, do you mean electrical Engineering ? Well it is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism.
Electrical engineering may or may not include electronics engineering. Electrical engineering deals 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 transmit information.
Then what is Mechanical Engineering? This has to do with the design of any mechanical system and the assembly of different mechanisms to form a machine.
This can be combined with other elements, such as the study and effect of heat in motion (Thermodynamics), the flow and application of compressible and incompressible fluid (Fluid Mechanism), mechanical design and computer/electronics engineering with the application of automatic control. (Mechantronics) etc.

Continuing on with what Colleen has mentioned above. A Mechanical Engineering degree opens more doors, that is, the career choices are not limited to just mechanics. Electrical engineering you are pretty much limited to electronic, power etc..........My partner is a qualified tradesman, he’s a Heavy Diesel Mechanic and is nearing his completion of his Mechanical Engineering associate diploma at TAFE. With the degree he is obtaining and his hands on experience, he is heading towards the consulting side of things. With his aim at working at some of the most prestige mine sites in Western Australia, his yearly salary is going to be massive..........So, for yourself, really weight up what you want to do. Ask yourself if mechanic related stuff is your kind of thing or if the electrical field is. From there, find what your passion is in regards to these two fields. What salary are you after and what positions you are striding for. Do you want to climb the ladder. Based on these, decide what you want to study.
Basically, electricity and mechanics...one deals in electrical science, the other is mostly physics
