It is the part of multimeter that shows the value of what is being measured.a.Indicator Pointerb.Scalec.Infinity Knobd.Zero Ohm Adjustment Knob

Break Down the Problem

1. Identify the function of each component listed in the question.
2. Determine which component shows the measurement value.

Relevant Concepts

• Indicator Pointer: Used to point to a specific value on a scale.
• Scale: The graduated markings on the multimeter where the values are indicated.
• Infinity Knob: Typically used for setting the multimeter to measure resistance.
• Zero Ohm Adjustment Knob: Used to calibrate the multimeter for zero resistance.

Analysis and Detail

1. Indicator Pointer: This is an essential component that shows where the measurement falls on the scale.
2. Scale: The scale provides the framework for reading values; however, it doesn’t independently display them.
3. Infinity Knob: This is primarily a setting tool and does not display measurements.
4. Zero Ohm Adjustment Knob: This is for calibration, not for displaying measurements.

Verify and Summarize

The primary component that displays the value of what is being measured on a multimeter is the Indicator Pointer, which works in conjunction with the Scale to indicate the value accurately.

Final Answer

The correct answer is a. Indicator Pointer.
