an electronic circuit detects open and short circuit

Dear Friends
I want to build a circuit that detect a short and open circuit between two wires. when the two wires are short, a led lights when open, led turn off.

Hello,

Perhaps this circuit is something for you.

If I'm getting it right then you should be able to do it very easily.

Just take a battery , connect it with a wire to LED . Put a switch and crocodile plugs in between and your circuit is ready.

Method to Test: Put the crocodile pins on the terminals of the circuit or wire arrangement. IF the Led glows circuit is intact and if doesn't it's open.

I hope it helped you.

Not quite. A current limiting resistor is needed to not burn out the LED.

Click to expand...

Are the wires attached to a device?...a circuit?...power?

This is a little old but it worked circa 1955, cable 13 twisted pair ,1400 ft,long. Normal procedure for breaks was to flex cable and hope to get a hit; slow and unrelyable; I designed a cable fault panel which switch select faulted pair: 1 check capacity vs good pair, with bridge ckt.to determine approx. distance; inject a 4kHz signal and with hand held high gain amplifier & head phones quickley found exact point of break. Could also measure resistance compaded to good pair to find approx location of short. No LEDs back then.
