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.
Normal Thyroid Levels for TSH. Thyroid function is measure base of the TSH range of TSH blood test. The normal thyroid levels for TSH used to be from 0.5 to 5.0. After clinical studies, in 2003, the TSH range has been revised to 0.3 - 3.0 as normal TSH levels.
