Does Sheet Thickness Affect Voltage Drop Measurement?

AI Thread Summary
The discussion centers on measuring voltage drop across a sheet with a resistance of 0.01 ohm per square when 1 Ampere is passed through it. It is clarified that the voltage drop can be directly read from a voltmeter, but the sheet's thickness does influence the overall resistance. A formula is provided for calculating voltage drop, which involves the sheet's length, current, and cross-sectional area. Understanding these factors is essential for accurate voltage drop measurements. The importance of thickness in relation to resistance and voltage drop is emphasized.

Hi

I am very confused how can measure voltage drop of a sheet if 1 Ampere is passed and the sheet has a resistance of 0,01 ohm in sq does it matter the thickness of the sheet ?

The voltage drop is whatever a voltmeter says it is. What's the problem?
 
The thickness is one of the determining factors of the overall resistanceD
 
He wants the pre calculated formula for plan review it sounds like:

Very simple srkn: 2k x length x I current / cm circular mil or its equal in sq in/mm = vd
 

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...
