DC to AC inverter using 555 timer

AI Thread Summary
The discussion focuses on the use of a 555 timer in a DC to AC inverter circuit and the necessity of power amplifiers for higher output. Participants inquire about the specific circuit referenced and the role of the two power amplifiers. It is noted that the 555 timer has limited power capabilities, necessitating additional amplification for effective performance. The lack of a visible schematic complicates the conversation. Understanding the integration of power amplifiers with the 555 timer is crucial for achieving desired output levels in inverter applications.

Your schematic is not available. The 555 is a relatively low power device, so if you require it to deliver much power output, you need to follow the 555 with a power amplifier.
 

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...
