<p style="text-align:justify">Electrical engineering&nbsp;(sometimes referred to as&nbsp;electrical and electronic engineering) is a professional engineering discipline that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply. Electrical engineering is now divided into a wide range of different fields, including&nbsp;computer engineering,&nbsp;systems engineering,&nbsp;power engineering, telecommunications,&nbsp;radio-frequency engineering,&nbsp;signal processing,&nbsp;instrumentation,&nbsp;photovoltaic cells,&nbsp;electronics, and&nbsp;optics&nbsp;and&nbsp;photonics.</p>

<p style="text-align:justify">Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering,&nbsp;power electronics, electromagnetics and waves,&nbsp;microwave engineering,&nbsp;nanotechnology,&nbsp;electrochemistry, renewable energies, mechatronics/control, and electrical materials science.</p>

<p style="text-align:justify">Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from&nbsp;circuit theory&nbsp;to the management skills of a&nbsp;project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple&nbsp;voltmeter&nbsp;to sophisticated design and manufacturing software.</p>
