Correct Answer: True
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.
Correct Answer: True
Explanation:
Filters that are designed to remove certain frequencies and allow others.
Band- pass filter - only frequencies in a frequency band are passed.
Notch filter - rejects just one specific frequency.
