The first bands give the resistor value's significant digits. The multiplier band gives the position of the decim
Why Is a High PH Bad in Your Body?
Human beings require a delicate balance of acidity in the body to perform various bodily functions. Your blood pH, the measurement of acidity, can vary based on food consumption or even when you have a cold or infection.
