1.	In a step up transformer, the turn ratio is 1:10. A resistance of `200 Omega` connected across the secondary draws a current of 0.5 A. What is the primary voltage?A. 5 VB. 10 VC. 20 VD. 2.5 V
Answer» Correct Answer - B `V_(s) = R xx I_(s) = 200 xx 0.5 = 100 V` `:. (V_p)/(V_s) = (n_p)/(n_s) :. V_(p) = 100 xx 1/10 = 10 V`.
