Given a voltage of 50 microvolts and a sensitivity of 10 microvolts/mm, what is the resultant amplitude?

• A. 0.2mm
• B. 5mm
• C. 0.2uv/mm
• D. 5uv/mm

Answer: (B)

To determine the resultant amplitude when given a voltage and sensitivity, the relationship between these two parameters must be understood. The sensitivity indicates how much the amplitude will be represented in millimeters on the electroencephalogram (EEG) display for a given voltage. In this case, a voltage of 50 microvolts is present, and the sensitivity is set at 10 microvolts per millimeter. To find the amplitude in millimeters, you divide the voltage by the sensitivity: Amplitude (mm) = Voltage (microvolts) / Sensitivity (microvolts/mm) Substituting the known values: Amplitude (mm) = 50 microvolts / 10 microvolts/mm = 5 mm Thus, the resultant amplitude is 5 mm. This calculation reflects how the graphical representation of the EEG signal correlates with the actual electric potentials measured, leading to the correct answer.
