A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

These resistors don’t matter much because the voltmeter is essentially an open circuit. No current flows so, therefore, there’s no voltage drop across the leads.

If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you cou… ...
