      Warning: Legalese in this post. Worth it though if naive to taxes and lotteries/drawings. Yes, eyeing at college students. Especially with debt in particular. Likewise, kids under 18 yrs old asking parents or someone older to enter for them.
      You may know this already but to others, one word. "Taxes". That why you read the terms and conditions. I'll even save time looking for it. "7. Taxes. All federal, state and/or local income and other taxes and duties, if any, are the winner's sole responsibility." Lots of people get giddy entering lotteries without planning out things which is sad but people will eventually live and learn. This is why in Tiers 1 and 2 you have a choice. As they have the most expensive price tags relative to Tier 3. Taxes are based on tax rate (based on how much you earn) and FMV (Fair Market Value) which is just a fancy term for how much the seller (i.e. Keysight) sets selling an item for.
      Selling online (e.g. Ebay, Craigslist, etc.) is not a guarantee of maximizing "profit" either. Especially after the Wayfair ruling (if in the U.S.A. unless lucky to live in 1 of 5 states with no sales tax). Wayfair essentially making most states able to collect online sales tax which would take yet another massive bite out of sales earnings (i.e. selling to a buyer in California, usually 9.75% or Texas usually 8.25% but can be lower depending on local laws). There is a such thing as a re-seller's permit that "excludes" this (doesn't feel different from the next sentence though) but doubtful Joe average entering on here even has one. As a seller you can compensate for that (by raising the price tag) however, that of course lowers the chances of a fast sell. Again, all this may or may not be legal depending on where you live. I don't live in other countries and therefore its your responsibility to know your country's tax code. Otherwise, expect fines too if you break the law! Usually, but there's also something called jail time too!
      Taxes and law are also partly why this drawing isn't even allow for whomever is watching. Best they can do is know someone willing to send them the winnings, move to another country allowing this or change lottery law in their country if that's the case. Lots of people ironically have gone bankrupt after winning something because they didn't know and went crazy with their winnings.....
      TL;DR: It doesn't hurt to dream but be realistic with your dreams. Its your responsibility after all as an adult 18 yrs or older.

    • @KeysightLabs

      So, what's happening is we're driving different current from the load, and then seeing how it impacts the voltage output. Ideally, the voltage would be completely DC under any load changes, but in real life the output changes (like we see at 4:53 )
