1.Forcapacitorchargeitisnecessarytotakeresistorwithresistance47Ohmand1Wattpower.
2.Measurevoltageofstabilizedpowersupply,whatwillbeusedtochargecapacitor(desirablepowersupplyvoltageis12-14V).
3.Multiplymeasured(received)powersupplyvoltageby0.67,forexample–14V*0.67=9.38V.Roundupandhave9.4V–itisvoltage,towhichcapacitorhastobechargedbyresistor.
4.Multiplydeclaredcapacitanceofcapacitorbyresistorresistanceandasaresulthavechargeequivalenttime.Forexample:itisdeclaredthatcapacitorvolume(capacitance)is1Farad,then47Ohm*1Farad=47seconds.Thiscapacitorhastobechargedto9,4Vin47secondswiththeuseof47Ohmresistor!
