ELECTRICAL GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
MULTIMETER USAGE - CONTINUED
(c) Multimeter "C" is used to measure voltage drop across a load, in this case a lamp. If voltages at multi-
meters "A" and "B" are 0.1 volt each, voltage reading at multimeter "C" will equal 23.8 volts. This is
because the sum of all voltage drops in a circuit is equal to the source voltage.
