How to measure the voltage across a resistor?
Understand the Problem
The question is asking for the method or steps to measure the voltage across a resistor in an electrical circuit. This typically involves the use of a multimeter or voltmeter and requires knowledge of circuit principles.
Answer
Use a digital multimeter (DMM) set to voltage measurement mode and place the leads across the resistor.
To measure the voltage across a resistor, use a digital multimeter (DMM). Set the DMM to the voltage measurement mode, then place the voltmeter leads across the two resistor leads.
Answer for screen readers
To measure the voltage across a resistor, use a digital multimeter (DMM). Set the DMM to the voltage measurement mode, then place the voltmeter leads across the two resistor leads.
More Information
Voltage measurement is straightforward with a digital multimeter. By setting the appropriate mode and ensuring proper contact with the resistor leads, one can accurately measure the voltage drop across the resistor.
Tips
A common mistake is forgetting to set the multimeter to the correct mode or not making proper contact with the resistor leads, leading to inaccurate readings.
