can VD actually be measured at the end of a
circuit while the amp load is on?Using a DMM.
Is this a accurate way to measure for voltage drop?thankyou

You can measure the voltage at each end of the loaded circuit and find the
difference.
Measuring at no load would be meaningless.

What about measuring open-circuit voltage (no load) and then voltage under
a known load? You can not only determine the voltage drop due to a
reference load (e.g., 15 or 20 amps) but the circuit resistance as well.
Isn't this pretty much what the Ideal testers do?
