AI Thread Summary
Clampers are circuits that limit voltage levels, primarily using diodes to protect sensitive devices from overvoltage. A diode clamp operates by allowing the output voltage to follow the input until a certain threshold is reached, at which point the diode conducts and restricts the output voltage to approximately one diode drop above the clamp voltage. For instance, when the input voltage exceeds around 5.7V, the diode becomes forward biased, keeping the output voltage at about 5.7V. Other passive clamp configurations exist, but they share the fundamental principle of voltage limitation. Understanding clampers is crucial for safeguarding electronic components from voltage spikes.

Can any genius tell me about Clampers.I am not able to understand it's working.

You mean like a diode clamp on a power line?
 
Clampers

yes But please tell me the working of Clampers
 
A diode clamp works by limiting the voltage to one diode drop above the clamp voltage, typically you want to protect the input to a sensitive device.

While Vin is below about 5.7V Vout will match Vin since the diode is reverse biased. With Vin above 5.7V the diode will become forward biased (i.e. it will conduct) and limit Vout to approx 5.7V. There are other passive clamp configurations but the idea is the same.

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...
