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.
if the tsh level is less than 0 3 the condition can be diagnosed as an overactive thyroid or hyperthyroid if the tsh level is above 3 then the condition is referred to underactive thyroid or hypothyroid the normal range for total t4 or total thyroxine is around 4 5 to 12 5he commonly preferred range of thyroid stimulating hormone tsh at most labs can be from 0 5 to 5 5 however some experts follow the recently updated reference range of 0 3 to 3 0
