If a unit has a pen deflection of 8 mm and a sensitivity of 5 uV/mm, what is the voltage?

• A. 25 uV
• B. 40 uV
• C. 50 uV
• D. 10 uV

Answer: (B)

To find the voltage given the pen deflection and sensitivity, you multiply the deflection (in millimeters) by the sensitivity (in microvolts per millimeter). In this case, the pen deflection is 8 mm and the sensitivity is 5 µV/mm. Calculating the voltage: Voltage = Pen deflection × Sensitivity Voltage = 8 mm × 5 µV/mm Voltage = 40 µV This demonstrates that when you know both the amount of deflection on the pen and the calibration sensitivity, you can effectively measure the voltage output. The result, 40 µV, corresponds to the choice that correctly represents the calculation based on the parameters provided.

Calculating the voltage:

Voltage = Pen deflection × Sensitivity

Voltage = 8 mm × 5 µV/mm

Voltage = 40 µV
