Voltage Drop and Resistance Measurement

A voltmeter is used to measure the potential difference between two points. A voltage drop is the difference in measured voltage between any two different locations on a complete circuit while a load is being operated. A voltage drop measurement is done by measuring the voltage before entering a load and the voltage as it leaves the load.
