The Daily Teaser — 16-5-2016: Electricity

Right …

It’s officially official.

I’ve got blood tests, today.

You’ll know — if you’ve been reading me for the past few weeks — my stomach’s been playing up.

Lord knows why!


I managed to pay a visit to my GP, a few days ago: who’s booked me in for some blood tests: which is hopefully going to show any problems with kidney and liver function.

Oh, and double check on my thyroid, as well.

I’m also due an ultrasound scan, as well: again, to check my kidneys.

Here’s hoping this shows SOMETHING …


But let’s move on, shall we?

Yesterday’s Teaser saw Olga* and Debbi† putting in their answers: with both scoring six out of six.

Let’s see how everyone does with today’s questions, shall we?

Here they are, along with the How To, License and video

Q1) 16th May, saw a lecture delivered by Nikola Tesla.   In which year?
Q2) The lecture was about transmitting electrical power, with what: direct current or alternating current?
Q3) Tesla backed one form of electrical distribution.   Which famed American inventor backed the other: Alexander Graham Bell, Thomas Alva Edison or Samuel Morse?
Q4) Tesla, himself, was born in what’s now which country: Serbia, Croatia or Macedonia?
Q5) Most forms of alternating current have a frequency of 50 — or 60 — what?
Q6) Which ticking item will depend — very heavily — on those frequencies?
Q7) The difference in electrical potential between two points — the force that makes electricity move through a wire, in other words — is called what: voltage, wattage or amperage?
Q8) What, exactly, is the standard SI unit of electrical power?
Q9) The mains electricity features a safety system.  Called what: Marsing, Venusing or Earthing?
Q10) Finally … if something can block or slow the flow of electricity, that’s known as what?
Here’s yesterday’s questions and answers …
Q1) Britain tested its first H-bomb.   On 15th May of which year of the 1950s?
A1) 1957.
Q2) The test device was dropped, where: Easter Island, Christmas Island or Saint Drogo’s Island?
A2) The BBC’s report for the day says Christmas Island.   I should point out that Wikipedia tells us the first in the series of test occurred on Malden Island: part of the same chain.
Q3) The series of tests were known as Operation what: Grapple, Grunt or Groan?
A3) Operation Grapple.
Q4) The test explosion weighed in at how big: 300 kilotons, 300 megatons or 300 gigatons?
A4) 300 kilotons.
Q5) In the UK, the tests inspired the founding of a protest group.   Which protest group?
A5) The Campaign for Nuclear Disarmament, or CND, as it’s better known.
Q6) Finally … the last of these bomb tests was the last bomb test carried out by the UK.   In which year of the 1950s was it carried out?
A6) 1958.
I’ll leave you with this thought …
“This planet, with all its appalling immensity, is to electric currents virtually no more than a small metal ball.”Nikola Tesla, 10 July 1856 – 7 January 1943.
And this tune …

Enjoy your day.

*        Now, why does that story not surprise me, Olga … ? :D

†        Oh, yes!   (Enjoy the video, Debbi: it’s fascinating to what what there is of the story.)

Q1) 1888
Q2) Alternating current
Q3) Thomas Alva Edison
Q4) Smiljan, Croatia (although to a Serb family. At the time part of the Austrian Empire. How things change! And how many times in some places)
Q5) Hertz
Q6) Electric clock
Q7) Voltage
Q8) Watt
Q9) Earthing
Q10) resistor
Fingers crossed for the tests, Paul. And I hope this week treats you better.
