Working with time constant RCA capacitor is used in the electronic flash unit of a camera. A small battery with a constant voltage of 6 V is used to charge the capacitor with a constant current of 10 microamperes. How long does it take to charge the capacitor when C = 10 microfarads? My Answer:V=6Vi=10mAC=10microFWc=1/2CV^2*(t)Wc=1/2(10^-5)6^2*(t)Wc=18*10^-5*(t)Wc=6V*.01A=.06JWc=.06J=18*10^-5*(t)t=.06/(18*10^-5)=333.33Final answer: 333.33 s
