Does Sheet Thickness Affect Voltage Drop Measurement?

Click For Summary

Discussion Overview

The discussion centers around the measurement of voltage drop across a sheet when a current of 1 Ampere is passed through it, specifically considering the impact of the sheet's thickness and resistance value of 0.01 ohm per square.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • Some participants express confusion about how to measure voltage drop and whether the thickness of the sheet affects this measurement.
  • One participant states that the voltage drop is determined by what a voltmeter indicates, questioning the nature of the problem presented.
  • Another participant suggests that thickness is a key factor in determining the overall resistance of the sheet.
  • A later reply offers a formula for calculating voltage drop, implying a desire for a straightforward method for practical application.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are differing views on the relevance of thickness and the nature of the voltage drop measurement.

Contextual Notes

Some assumptions regarding the relationship between thickness, resistance, and voltage drop may not be fully articulated, and the discussion includes varying interpretations of the measurement process.

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
