A) 0.24 V
B) 0.08 V
C) 240 V
D) 2400 V
Correct Answer: B
Solution :
The transformation ratio of a transformer is given by \[\frac{{{V}_{S}}}{{{V}_{P}}}=\frac{{{N}_{S}}}{{{N}_{P}}}=r\] where\[{{V}_{S}}\]and\[{{V}_{P}}\]are voltage across secondary and primary and\[{{N}_{S}}\]and\[{{N}_{P}}\]are number of turns of secondary and primary respectively. Given, \[{{N}_{S}}=3000,\text{ }{{N}_{P}}=1000,\text{ }{{V}_{p}}=80\text{ }V\] \[\therefore \] \[{{V}_{S}}=\frac{3000}{1000}\times 80=240V\]You need to login to perform this action.
