Electrical Theory

Licensed Electrician or Technician is expected to have strong knowledge in Electrical Science concepts. Normally electricians will be carrying out works related to installation of new electrical components, maintaining or repairing the electrical infrastructure. For carrying out these duties NEC code books, thumb rules and other calculation resources will be referred. But in-order to understand the work in depth knowledge in electrical basics is required. Electrical Basic Theory is tested in almost all the License exams for understanding the ability of the electrical knowledge of the candidate.

In this section a pool of electrical topics ranging from atomic structure, ohm’s law to AC machines are covered. This section will helps in brushing up your knowledge in basic electrical concepts. Each practice test consists of 15 to 20 multiple choice questions (MCQs) with answers. Along with the practice tests, electrical concepts were explained when and where required. Please go through the Free Practice Tests provided. Some of the important topics in this section are:

  • Ohm’s Law
