AI Thread Summary
The discussion centers on a user experiencing voltage drops from a 12V battery powering a DC booster circuit, which outputs approximately 40V. The user seeks solutions to prolong battery life without voltage loss but lacks specific details about the battery's energy rating and the current draw from the circuit. Participants are requesting information about the battery's Amp-hour rating, the current being drawn, and the load specifications of the booster circuit. The conversation emphasizes the need for precise data to diagnose the issue effectively. Overall, understanding the battery's specifications and the circuit's demands is crucial for addressing the voltage drop problem.

I use a 12V battery to power a DC booster circuit. After just a moment, my battery's voltage decreased, causing the booster circuit to also decrease its voltage. Is there any way to make the battery last longer without losing voltage? Thanks

What is the energy rating of your battery (in Amp-hours)? What current do you measure out of the battery when it is driving the boost circuit? What is the load of the boost circuit (output voltage and current)?

The output voltage of the booster circuit is about 40V, and I don't know what the energy rating of the battery is (I use a GP 23A 12V battery).

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...
