The ideal level of current ratio is
(a) 1 : 1(b) 2 : 1(c) 1 : 2(d) 3 : 1Correct option: (b) 2 : 1The ideal level of current ratio is 2 : 1.
In an ideal step-up transformer, the ratio of turns of primary to secondary is 1:10 and primary voltage is 230 V. If the load current is 2A, then current in the primary is
