[BC] Total Power Of An AM Directional Array

[Tom]

In an AM multiple tower directional array, does the power of 
all towers as determined by "P equals I squared times R" add 
up to the authorized power of the station?

For example, for a one thousand watt station with four towers 
would the power of each tower add up to one thousand watts?

Thanks to all who have answered my occasional questions to 
satisfy my curiosity about radio, even if the questions 
appear to be dumb ones.
