how to construct a low voltage protection system using annunciator?
"low voltage protection system using annunciator
generate 5volt power supply from 230volt ac and activate beeper when
power supply is below 180volt.choose components with appropriate
materials.list the important property based on which the material is
chosen for the components .draw the waveforms of current and voltage
at specific branches and node.find the laplace transformations ."
so if any one does come across some ideas please help i have my first review coming by so reply ASAP guys
