Question

R1 28 2 (1 E1T5V If sw is closed at to find and plat ucandic

and give thevinin solution

Answer 1

given circuit is w for too of R-c circuit we know that Stelo expression defines - tydloo) Valt) = frelot) – velos se where time writont 23 RC secund step o concept using transient Anolysis a t=0 open circuit of short circuit => > capacitor will replaced by inductor will reffaced deg → new circuit becomes 딱 밖 어 btu, 10-) > = 9 volt using kve - -V + 5+ 2x2 =D

from the alove circuit 10-120 Volt Spepo at tot from the properties of copacifor, it con not allow to sudden change in voltage. V10) cre lot) = 0 volt that means step at +=0 using transient Analysis concept Capacitor will crets as a open circuit then new circuit becomes Tov ♡ Ive (0) using len [u= q volt Again uning kve - y + 3x0 Ave 10) ='0 -Tula) - 9 volt)

( source for R at tso - Also known as equirelent resistence. - plik independent voltage sounce gets short C circuit & all independent chorent I gets open circuit s will appear acerosa copacilor. then new circuit becomes - 5 n = unit step signol from 6 - velt) - fyclo) +{verot) – Veloso e se ne Juh, iso 9 + lo colest itao velt) = 9 volt itao - t 7 Avelti Telt) = c dvelti - cel ulty = ge dit) 에 impulse signal whose sti= pleto 19
