ChaCha Explains Electricity

I asked ChaCha about electricity and power failures:

Me: ChaCha, why does the power go out for just a few seconds, then come back on?
ChaCha: There is an inconsistent amount of power entering your house.

ChaCha never ceases to amaze! So, if I understand this correctly, the power went out because the supply of power to my house is inconsistent. In other words, the power went out because it had previously been supplying power, but then it stopped supplying power, and then it started supplying power again. Genius!
