Why don’t transformers work with direct current? Answer: Transformers don’t work with direct current (DC) because they rely on the changing magnetic fields generated by alternating current (AC) to induce voltage across coils, a process not present in steady DC. Reasoning: Transformers operate based on Faraday’s law of electromagnetic induction. …

Why Delta Configuration Is Preferred Over Star Configuration in Motor Applications? Answer: Delta configuration is preferred over star configuration in motor applications due to its ability to provide higher starting torque, reduced voltage drop, simplified control, reduced current imbalance, space and weight considerations, potential cost efficiency, and suitability for induction …

Which Current Is More Dangerous AC or DC? Answer: In terms of physiological effects on the human body, AC (Alternating Current) is generally considered to be more dangerous than DC (Direct Current) at certain frequencies and amplitudes. This is primarily due to the “let-go” phenomenon and the potential for sustained …
