Question

How are power thinking and critical thinking different?

Answer 1

I'm not so sure you are asking a serious question, but here are my answers:

Power thinking is kind of like this:

Terminology:

V = Volts (potential energy)  (outlet voltage standards: http://www.kropla.com/electric2.htm)

A = Amperage or Amps (electric current)

VA = Volt-Ampere (apparent power)

PF = Power Factor (ratio of real power to apparent power) [number between 0 and 1]

W = Watts (active or real power)

And Some useful functions:

V = VA / A

A = VA / V

VA = V x A or VA = W / PF

PF = W / VA

W = VA x PF

And an interesting way to look at this entire span of relationships:

V x A --> VA x PF --> W

or backwards

W / PF --> VA / V --> A  (typically you already know the Volts; like outlets in USA are 120V or batteries have their indicated Volts on them)

Example (My PC when Idling):

(119V x 2.25A = 268VA) x 0.66PF = 177W  (actual math: V * A * PF = W)

or

(177W / 0.66PF = 268VA) / 119V = 2.25A  (actual math: (W / PF) / V = A)

For further information... check out these terms on http://www.wikipedia.org/

Hope this is of use to some people.

Critical Thinking is like this:

Someone holds a gun to your head and asks you questions and if you answer them wrong, your done for.  If that ain't critical thinking then I don't know what is?
