Transformers problems
- 1. The primary is the winding connected to the source, and the secondary is the winding connected to the load.
Options- A. True
- B. False Discuss
Correct Answer: True
- 2. A center tap (CT) is a connection at the midpoint of the secondary winding of a transformer.
Options- A. True
- B. False Discuss
Correct Answer: True
- 3. If the voltage is stepped up, the current is stepped down, and vice versa.
Options- A. True
- B. False Discuss
Correct Answer: True
- 4. A step-down transformer has a turns ratio less than 1.
Options- A. True
- B. False Discuss
Correct Answer: True
Explanation:
Ns/Np is known as the turns ratio.
In step down transformer the number of turns in secondary winding (Ns) will be less than the number of turns in primary (Np).
Therefore, the ratio will be less than 1 for step down transformer.
Ex: Np = 10, Ns = 5; Turns ratio = 5/10 = 0.5.
In step down transformer the number of turns in secondary winding (Ns) will be less than the number of turns in primary (Np).
Therefore, the ratio will be less than 1 for step down transformer.
Ex: Np = 10, Ns = 5; Turns ratio = 5/10 = 0.5.
