    I need help on this question.

    A single phase system is rated at 300kva and 11kv. using these as base values, find the base current and base impedance. And using 10mva and 345kv as base values for a single-phase electric network, express 138kv, 6mva, 250a and 50 ohms in (i) per unit and (ii) percent values.
