3. Which component in a transformer is responsible for transferring the magnetic flux?
Submit
4. What is the typical frequency of electricity used in most countries?
Submit
5. What is the purpose of grounding in a transformer?
Submit
6. What is the formula to calculate the voltage ratio of a transformer?
Submit
7. What is the phenomenon called when a transformer produces an electric current in its secondary coil due to a changing magnetic field in the primary coil?
Submit
8. What is the role of a tap changer in a transformer?
Submit
9. Which property of an AC current allows transformers to work?
Submit
10. What is the unit used to measure the apparent power of a transformer?
Submit
11. What happens to the current in a step-down transformer?

Explanation

In a step-down transformer, the voltage is decreased on the secondary side compared to the primary side. According to the principle of conservation of energy and the transformer equations, when the voltage decreases, the current increases, provided that power remains constant (neglecting losses). Therefore, the current in the secondary winding of a step-down transformer increases relative to the primary winding.

14. What is the function of the transformer oil in a power transformer?
Submit
15. What is the unit used to measure the power output of a transformer?
Submit
16. What is the primary function of an electricity transformer?
Submit
17. What is the name given to the phenomenon where a transformer produces a high voltage spike when the input power is suddenly interrupted?
Submit
18. What is the main advantage of using a transformer in electricity transmission?
Submit
19. Which of the following is the primary function of an electrical transformer?

Explanation

The primary function of an electrical transformer is to increase (step up) or decrease (step down) voltage levels in an AC (alternating current) electrical circuit. Transformers work on the principle of electromagnetic induction and are essential for efficient power transmission and distribution over long distances. They do not convert AC to DC, store electrical energy, or measure electrical current.
