Answer 1

The giver graph is - Io sin Cust-1/2) ad Io=4 i= 4 sin fent -1/2) from the graph we can see that time Period of one cycle is 60 sec To set => warmo To rednec &= 4 bin (7 t - 772) the voltage across generater is equal to valtage acreen inductor as they are berralld. 30 VL = L di = L.4 Cas (A x - 72) 7/10 x = 4L A Can ( 7 * - 1/2) ist has the beak vakre if Cas O = 1 means O= Th Hence - I = 72 = * = * = (t = 30 sec] Vmax = 4 LI = 0.1V Hence L= 0.1x30 [L=0.239 Ang 47
