OK, first we need to find the voltage output (secondary voltage) then multiply by the current as #P = V xx I#

Explanation:

The (ideal) transformer equation will give us the value of #V_2#

#V_1/V_2 = N_1/N_2# where N is the number of turns or coils.

We have: #200/V_2 = 250/500# so rearranging we get

#V_2 = 200 xx (500/250) = 400#V

Now for the power output, #P = V xx I#

So #P = 400 xx 5 = 2000#W or 2kW
