Which of the following steps is necessary to measure the capacitance of a capacitor using an LCR meter?

Option 1: Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and turn on the meter.

Option 2: Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and set the meter to the proper range.

Option 3: Disconnect the capacitor from the circuit, turn on the meter, and set the range selector switch to the proper range.

Option 4: Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and read the capacitance value directly from the display on the front panel.

Final answer:

The correct procedure involves disconnecting the capacitor from its circuit, connecting the meter's leads to the capacitor's leads, and setting the LCR meter to the appropriate range (Option 2).

Step-by-step explanation:

To measure the capacitance of a capacitor using an LCR meter, the correct steps include: Option 2: Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and set the meter to the proper range. This process ensures safety and accuracy.

It is crucial to first disconnect the capacitor from the circuit to prevent measuring the equivalent capacitance of the entire circuit or causing damage to the meter. Then, the meter's leads must be securely connected to the capacitor's leads.

Lastly, setting the meter to the correct range is essential for obtaining a precise measurement. LCR meters are capable of measuring a range of capacitance values, and selecting the proper range helps avoid overloading the meter and ensures the display will show a value within its measurable limits.

Final answer:

To measure the capacitance using an LCR meter, disconnect the capacitor from the circuit, connect the meter's leads to the capacitor, turn on the meter, set it to the proper range, and read the value from the display.

Step-by-step explanation:

To measure the capacitance of a capacitor using an LCR meter, certain steps are necessary. First, you must disconnect the capacitor from the circuit; this is important because you want to measure the capacitance of the capacitor only, not the entire circuit. Then you connect the meter's leads to the capacitor leads, carefully observing the correct polarity if it is a polarized capacitor. After this, you need to turn on the meter and set it to the appropriate capacitance rangeā€”if your meter has a range selector. Lastly, you can read the capacitance value directly from the display on the front panel of the LCR meter. Therefore, Option 2 that says 'Disconnect the capacitor from the circuit, connect the meter's leads to the capacitor leads, and set the meter to the proper range.' combines all the necessary steps and is the accurate answer to the question.
