How to use zener diode as voltage regulator
Why zener diode as voltage regulator Because a Zener diode is used as a voltage stabiliser or voltage regulator to provides a constant voltage from a source whose voltage may …
Wien’s displacement law formula
According to wien’s displacement law, the wavelength (λm) corresponding to maximum energy density is inversely proportional to the absolute temperature (T) of the body. This is called wien’s displacement law …
