Electrical engineering is one of the oldest and most fundamental branches of engineering, focusing on the study, design and application of electricity, electronics and electromagnetism. From powering cities and communication networks to developing the microprocessors inside your smartphone, electrical engineering is indispensable to modern life. It provides the technological backbone for nearly every industry, defining how energy is generated, transmitted and consumed.
At its core, electrical engineering deals with the mass production of electrical power, its control and its practical applications. The field covers an enormous range of scales, from massive power generators and regional transmission grids to tiny electronic circuits and nano-scale devices.
A professional in this field, an electrical engineer, designs and develops:
The knowledge base required for an electrical engineer relies heavily on physics, mathematics (especially calculus and differential equations) and computer science principles.
To enter this dynamic field, one typically pursues an electrical engineering degree. The most common entry point is the undergraduate level.
The electrical engineering bachelors degree (typically a Bachelor of Technology (B.Tech) or Bachelor of Science in Engineering (B.S.E.) is the standard four-year qualification required for professional practice.
Students often choose advanced electives in their final year to specialize in areas like microelectronics, communications or electrical power engineering.
The vast scope of the discipline means electrical engineering is often broken down into several specialized fields.
Electrical power engineering is arguably the most recognizable sub-field, dealing exclusively with the generation, transmission, distribution and utilization of electric power. This area focuses on large-scale systems and high-voltage applications.
This field, closely related but often distinct, focuses on smaller-scale applications, particularly circuit boards, semiconductors and signal processing.
Key Focus: Designing integrated circuits (IC), microcontrollers, electronic sensors and digital logic gates.
Engineers in this area design systems that regulate the behavior of other devices.
Key Focus: Robotics, automotive control systems, industrial automation and developing algorithms for feedback loops.
This involves the transmission and reception of information across various media.
Key Focus: Developing wireless protocols (5G), designing antennas, coding and decoding information and optical communication networks.
A degree opens doors to diverse career opportunities across many industries, including energy, defense, telecommunications and manufacturing.
Electrical engineering companies range from small, specialized startups focusing on chip design to multinational corporations building global infrastructure. Major employers often include:
Regardless of the specialization, all electrical engineers must master several basic electrical engineering concepts:
| Concept | Description | Mathematical Relation |
|---|---|---|
| Ohms Law | Defines the relationship between voltage (V), current (I) and resistance (R) in an electrical circuit. | V = I X R |
| Kirchhoffs Laws | Fundamental rules for analyzing circuits, governing current conservation (KCL) and energy conservation (KVL). | Iin = Iout (KCL) |
| Power | The rate at which electrical energy is transferred, measured in Watts (W). | P = V X I |
| Electromagnetism | The principle that electrical current produces a magnetic field and vice versa, which is essential for motors and generators. | Governed by Maxwells Equations. |
These fundamental principles form the backbone of both complex electrical power engineering systems and detailed microchip designs.
While the B.Tech degree qualifies one for design and management roles, the electrical engineering tech (Technician) plays a crucial hands-on role.
In many electrical engineering companies, the technician and the degreed engineer work closely together-the engineer designs the system and the technician ensures it is built and maintained correctly in the field.
