How to measure voltage drop

  1. Jul 3, 2014 #1

    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 resistance

    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
