Over 18 years old only
It means no one under 17 admitted. Even if accompanied by a parent or guardian. The old X rating is now the NC17 rating. Back in the day the X rating was given for extreme violence (Robocop got an X rating at first, until they trimmed a lot of the shotgun killing at the beginning.), extreme gore (The first Dawn Of The Dead was rated X, until Romero decided to release it unrated) or for pervasive sexuality (Midnight Cowboy was rated X, and was the first X rated movie to win an oscar. It has since been re-rated as a R The same with Fritz The Cat which added drug use to the sex.) It almost sounds like the X rating is a catch-all for anything someone at the ratings board is bothered by, doesn't it?

Wattage or power rating of a product can be calculated by multiplying voltage rating and current rating. (Power = Voltage x Current). e.g. if device is working at 12V and 2A is the current rating. It is 24Watt. Since Voltage = Current x Resistance , for a resistive load power can also be calculated by Power = Current x Current x Resistance = I^2 x R = I square R
It's a speed rating, in this case meaning 'up to 130 mph'.
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
