if your circuit is correctly derived from whatever it was initially:

- you will have no potential at the output terminals as they are shorted at the two nodes marked "A"
- the total resistance (Rt) is two 1k ohm in parallel (500 ohm) in series with a 1k ohm = 1.5 k ohm , they will carry current you can calculate.

Further I know when resistor is parallel with wire(short circuit ) the current through that resistor is equal zero , is it by somehow that is the reason the voltage through that resistor is equal to zero too!!) ....
My teacher in tech school told us that electrons are like lazy Boy Scouts- they will take the path of least resistance. He also said to consider resistors like mountains. The lazy Boy Scouts are hiking along, and come to a split in the path. One way is nice and level, the other goes over mountains. Which path will the (lazy!) Boy Scouts take? Correct! They will go hiking the easy way!

And because there are no Boy Scouts (electrons) passing over the mountains (resistor) there are no voltage (sweat??) drops.

Yeah, it's a silly picture, but it HAS stuck with me for twenty years!

dear miss, have you read about kirchoffs voltage law!!! try applying it and you will end up with the answer. basically remember, current always tries to take a least resistance path in case of parallel resistors, and the short circuit is the least resistance path in your figure...
i would like to know what you think of it...

im sure shes going to find this useful 5 months later ;)
