What can you conclude about this switching network when switch is open and switch is closed? Justify you’re answer.

Answer 1

What can you conclude about this switching network when switch P is open and switch Q is closed? Justify you’re answer.

Answer 2

Oh this is a neat problem :)

Answer 3

If `switch P` is `open`,
what can you say about `switch not P` ?

Is it open or closed?

Answer 4

It's open

Answer 5

Nooo silly!

If `switch P` is `open`,
then `switch not P` would be in the opposite state, yes?

Answer 6

Maybe I can say it this way,
`switch P` is `open`
therefore,
not `switch P` is not `open`
which translates to,
`switch ~p` is `not open`
`switch ~p` is `closed`

Answer 7

So the answer isn't really based on the picture then? All the switches are open in the picture

Answer 8

Correct :) It's not based on the picture's current state.

Answer 9

Ohhhh so this "(~q V ~p) V (p ʌ q) ʌ ~p" is completely wrong then? I tried to come up with the symbolic statement based off the picture

Answer 10

They told us that p is open, we have to use that to figure out how the other doors should be positioned.
