A neon sign requires a current of 106 mAo-p at 12900 Vo-p. This means it needs Arms at Vrms- Assume it is to be plugged into a standard 120 V household outlet. It needs an ideal transformer with a turns ratio of :10. This transformer would require a primary current of Arms, and would draw W of power. If it were to be plugged into a standard 240 V outlet, the ideal transformer would then require a turns ratio of :10, a primary current of Arms, and W of power.
