VOLTAGE
DROP
A voltage drop is the amount of voltage or electrical pressure that
is used or given up as electrons pass through a resistance (load). All
voltage will be used up in the circuit. The sum of the voltage drops
will equal source voltage. A voltage drop measurement is done by measuring
the voltage before entering the load and the voltage as it leaves the
load. The difference between these two voltage readings is the voltage
drop.
