Hans Christian Oersted and Ampere discovered that electric current flowing through a conductor produces a magnetic field around it. Michael Faraday thought that the reverse effect of that should also be true. i.e A magnetic field must produce an electric current. Electromagnetic induction is defined as the process of producing an induced current in a … Read more
Electrical Engineering MCQs on Power Transmission Part 29 In DC transmission, the skin effect is In DC transmission, the skin effect is: Correct answer: 1. Zero Explanation: In case of DC system the direct current is uniformly distributed over the whole X-section of the conductor. Therefore a DC system has no skin effect and the entire cross-section of … Read more
