Tips: 60Hz vs 50Hz
The choices of 60 Hz (Hertz) and 50 Hz (Hertz) were both rather arbitrary. (There's no RMS difference) Lower electrical frequencies require more iron in their transformers because the magnetic fields that accompany their AC currents change less rapidly and so saturate the iron more readily. On the other hand, the changing magnetic fields induce eddy currents in the iron core that obviously increase with the increased rate of change caused by higher AC frequencies. The same trade-offs apply to electrical motors too. (And that's why airplane power systems where weight is important use much higher frequencies, 400 Hz.)

So, generally 50 Hz transformers/motors have higher initial costs but lower operating costs and longer lives. It is generally accepted that Nikola Tesla chose 60 Hz as the lowest frequency that would not cause street lighting to flicker visibly. The origin of the 50 Hz frequency is open to debate but seems likely to be a rounding off of 60Hz to the 1, 3, 5, 10 structure popular with metric standards.
