Thomas Edison often referred to himself deaf, but that isn't exactly true. He was very hard of hearing though. Edison told a story of being picked up by his ears to keep from falling off of a train, saying at the time he heard something "pop" inside his ears. However, experts seemed to think it was a type of hereditary hearing loss, as both his father and his brother had similar conditions.

Why transformer are rated in kVA instead of KW?
Transformers are rated in VA or kVA. That is because the voltage is limited by the power loss in the magnetic core, and the current is limited by the power loss in the resistance of the windings. The rated voltage times the rated current gives the transformer's rating in kVA.
