CONGRATS TO Jacob Kaufman, Alaska License #147761
for winning this weeks QOTW. Good job!
Follow the directions to obtain your books.

SPECIAL mention to Kirk Bauer for having the same answer I was thinking on the tennis ball! :cowboy_hat_face:

  1. North pole induces _______
    a) Anti-clockwise current
    b) Infinite current
    c) Zero current
    d) Clockwise current
    a) Anti-clockwise current
    A north pole will always induce an anti-clockwise current whereas a south pole will always induce a clockwise current due to electromagnetic theory

  2. Why is it important to have a grounding conductor on all electrical cords?
    a) Helps protect the person using the cord from electrical shock
    b) Helps route current through the supplied ground instead of the person
    c) Current will always take the path to ground with the least resistance
    d) a-c
    e) a-b-c
    a)
    Answer B makes it sound as if the current will only go through the equipment grounding conductor (EGC) and not the person, this is not true. If the EGC and the person are both parallel paths then the current will flow though both of them, since the EGC should have a lower resistance more current should flow on it but not all of it as the answer implies.
    In C that answer is false because it implies that current will only follow the path of least resistance, this is false because the current will follow all parallel paths regardless of the path’s resistance.

  3. A conductor differs from an insulator in that a conductor
    a) has an excess of electrons
    b) can become charged and an insulator cannot
    c) does not have any neutrons to get in the way of electron flow
    d) b-c
    e) none of the above
    e)

  4. On voltage increase, what happens to dielectric strength?
    a) Increases
    b) Becomes zero
    c) Decreases
    d) Remains the same
    a) Increases
    Dielectric strength is the potential gradient required to cause a breakdown in the material. Potential gradient is the ratio of voltage and length. Hence as potential increases, dielectric strength also increases

  5. If you were to throw a tennis ball 26.5 feet, why could it ever come back to you? :tennis:
    You threw it directly up

    O K !

WHO sang this on WHAT song?
Must be those strangers that come every night . . . :alien:

*Must be those strangers that come every night *
*Whose saucers shaped light put people up tight *
*Leave blue green footprints that glow in the dark *
I hope they get home all right

Congratulations Jacob.

Way to go, Jacob! Nice win! :smile:

Follow the directions in the first post for your books.

Wooo!!! Alright!
Thanks guys!! I love doing these every week. I wasn’t giving up until I got it haha. I’ll be here again next week!
Thanks @mgoldenberg for taking your time to do these week in and week out. It’s not the questions, it’s the effort to answer these that makes them enjoyable!

Grats Jacob… I agree with you that it’s the effort to research/answer the questions that’s the enjoyable part. Usually learn other things as well besides just the asked questions

Congrats Jason! Good questions Marc, thanks for your time!

Thanks again guys!

Congratulations Jacob!
