Answer:
1:2
Explanation:
It is given that,
Initial RMS AC voltage is 100 V and final RMS AC voltage is 200 V.
We need to find the ratio of the number of turns in the primary to the secondary for step up transformer.
For a transformer, ![\dfrac{V_1}{V_2}=\dfrac{N_1}{N_2}](https://tex.z-dn.net/?f=%5Cdfrac%7BV_1%7D%7BV_2%7D%3D%5Cdfrac%7BN_1%7D%7BN_2%7D)
So,
![\dfrac{N_1}{N_2}=\dfrac{100}{200}\\\\\dfrac{N_1}{N_2}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7BN_1%7D%7BN_2%7D%3D%5Cdfrac%7B100%7D%7B200%7D%5C%5C%5C%5C%5Cdfrac%7BN_1%7D%7BN_2%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
So, the ratio of the number of turns in the primary to the secondary is 1:2.
