Hi I am having trouble relating power to the electric field amplitude, I know that P=IA and E=cB, could someone please help? The problem reads:

What electric-field amplitude is required to transmit an amount of power equal to that handled by modern transmission lines (that carry voltages and currents of 500 kV and 1000 A)? Suppose power is to be transmitted in a beam of cross-sectional area 100m^2.
