suppose i have "n" number of wire and all are independent to each other which connected to other terminals........ my problem is " if any short or open circuit occur among the wires, HOW WILL WE CHECK THAT?????? just by glowing of DIFFERENT colour of LED
like RED coressponds to SHORT
BLUE coressponds to OPEN
:cry:
 

you may connect a 10K resistance in series with LED for detection purpose.
 

i got the idea for open circuit......... but how we check short circuit?... it should be in automatic sense.....:idea:
i need some clear explanation

led may operate at a voltage less than 3 so dont forget to put a 3 K ohms resistor in series with the red led. and for the blue led, there is no need to do that, you will need an extra cct to detect the open cct, i believe that when the red led does not work, is a good indication the you have an open cct
 

Hi Riku,

Here's your circuit, it contains two led's, a resistor,
a switch and a battery.
Short condition: Red led lights.
Open condition: Green led lights.
You can even replace both led's with one bicolor led.
