20 dollar circuit problem
The solution is under $20, so you can forget about some high tech remote control electromagnetic thingie...
(the question was directed at the electrical engineering students, so don't feel bad if you can't solve it)

boss, but it is in serial leh... (sort of)

turn it into a parallel circuit but adding 2 wires, one connecting lamp A to switch A, and one connecting lamp B to sources.
correct?

sounds correct...
i'll only hear the answer tomorrow =P

seems that its a parallel circuit, with LA and switch A on one side, LB and switch B on the other line.

what if you can't connect anything beyond the boxes?

On my first read, I thought it was a trick question...
The circuit inside each box is unknown. Now find the unknown.
==>It is inside each box

LOL, I'll see what's the correct answer when I attend the lecture tomorrow =)
