AI Thread Summary
To create a circuit where an LED lights up when a wire is unplugged from a battery, a resistor should be placed in front of the LED to prevent battery drainage while the circuit is complete. The LED will remain off when the middle wire is connected, as the current will follow the path of least resistance. When the wire is removed, the circuit is interrupted, allowing the LED to light up. The goal is to ensure that the LED is typically off and only activates upon disconnection. This setup effectively meets the requirement without draining the battery.

Hello all. I am trying to build a very simple circuit and need some help.

I want to have an LED connected to a battery, and if a wire is unplugged from the circuit then the LED lights up.

Does anyone know how I can make this happen?

Here is a picture of a schematic that gets the job done, but it drains the battery.

Ok, see the middle wire? While that middle wire is connected the led will not light up because the current will take the path of least resistance. So I would probably put a resistor in front of the LED.

But if you remove the wire the LED lights up.

So the LED should typically not be lit, but if I unplug a wire then the LED lights up.

That's all I need! But without draining the battery of course!

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
