Electrical engineering is one of the newer branches of engineering, and dates back to the late 19th century. It is the branch of engineering that deals with the technology of electricity. Electrical engineers work on a wide range of components, devices and systems, from tiny microchips to huge power station generators. An electrical engineer is someone who designs and develops new electrical systems, solves problems and tests equipment. They study and apply the physics and mathematics of electricity, electromagnetism and electronics to both large and small scale systems to process information and transmit energy. They work with all kinds of electronic devices, from the smallest pocket devices to large supercomputers. Of late the stream of electrical engineering is sub-categorised into many sub streams like electronics, digital computers, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics.
A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
Every IES exam is divided into two sections -
Paper I & Paper II .
While paper I remains common for all the branches/streams of engineering, the paper II is specialised with respect to the branch of engineering students.
Indian Engineering Services(IES) include technical and managerial services for government of India. The pay scale of Indian Engineering Services is as high as the pay scale of IAS officers. After 7th pay commission, an IES officer with their esteemed cadre receives more benefits along with high salary and varied allowances and benefits.
The recruitment of qualified candidates are made under the following sectors:
Electric and magnetic fields, Gauss's Law and Ampere's Law, Fields in dielectrics, conductors and magnetic materials, Maxwell's equations, Time varying fields, Plane-Wave propagating in dielectric and conducting media, Transmission lines.

The online preparation for IES Electrical Engineering 2020 by VANI Institute in association with AspireBuzz has been designed by top educators from reputed universities and is available in two packages to the IES Aspirants. The topics are meticulously curated by our proficient and well-experienced senior Professors/Lecturers of Vani Institute across the country identifying the critical topics for subjects from IES assessment perspective. A student appearing for IES Electrical 2020 can evaluate and choose the model that suits him/her the best:
This module is designed to help you solve the tests for Online Preparation on IES 2020 Civil and understand the concepts associated with the questions provided. AspireBuzz follows the principle of Stimulation Based Learning, an unique interactive module, where the aim is to stimulate our conceptual analysis and reach to the solution on our own rather than the direct answer approach. Each question in this test series is accompanied by three videos:
[Please Note: All the videos are exclusive to Aspirebuzz and VANI Institute and are created by the faculty from premier institutes across the country.]
This package is ideal for students who are already preparing for the UES and are looking towards further robust enhancement in the preparation for IES 2020 Electrical through online preparation mode. The package comes along with multiple questions for the students to perform and solve. Each question is accompanied with a solution. The solutions available are in a relevant text format in this package and so does not need or contain any videos.
You can very well anytime, anywhere register for a free demo/trial package with our learning platform AspireBuzz and let your journey for Online Preparation of IES 2020 Electrical begin.
