Voltage is analogous to pressure, so the voltage rating is the same thing as the pressure rating on a pressurized tank. If you apply too much pressure, both a capacitor and a tank will explode.
Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range. This is based on the test, the equipment being used, and the patients being tested.
