The turns ratio of transformer is 10, It means that:
- A
Is=l01p
- B
Ns=Np/10
- C
Ns=10Np
- D
Vs=Vp/10
NP/NS = VP/VS = IS/IP
The current in the secondary winding is not proportional to the number of turns
The number of turns in the secondary winding is proportional to the number of turns in the primary winding, not inversely proportional
In a transformer, the turns ratio is defined as the ratio of the number of turns in the secondary coil (Ns) to the number of turns in the primary coil (Np). In this case, the turns ratio is given as 10, which means that the number of turns in the secondary coil is 10 times the number of turns in the primary coil.
This relationship is important because it determines the voltage transformation in a transformer. According to the turns ratio, the voltage in the secondary coil (Vs) is proportional to the voltage in the primary coil (Vp) by the same factor as the turns ratio. So, if the turns ratio is 10, it means that the secondary voltage is 10 times the primary voltage:
Vs = 10Vp
Therefore, the correct statement is Ns = 10Np.
The voltage in the secondary winding is 10 times the voltage in the primary winding, not 10 times smaller.
