The magnetic energy stored by a coil carrying a current is given by one half of the inductance of the coil times the square of the current

The geometric mean is a type of mean or average, which indicates the central tendency or typical value of a set of n numbers by using the product of their ... more

For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result. ... more

The degree of dissociation of a weak electrolyte is proportional to the inverse square root of the concentration, or the square root of the dilution
