18. An ideal 50-Hz, core-type transformer has 100 primary-turns and 200 secondary- turns. The primary rated voltage is 220 V. If the maximum permissible flux density is 1.2 T, what should be the cross-sectional area ? Also, find (a) the secondary voltage, and (b) the primary current in complex form with reference to the secondary voltage vector when secondary delivers a current of 8 A at a lagging power factor of 0.8.
