Q- find V1(t) for t >0 well im bit confused about the signs and thats y my secondorder differential equation differs in terms of signs (+ &-)only..i dont know what mistake i m making with the signs..im alsoconfused that if i use polarities for inductor and capacitor for (t< 0-)..will i have to use the same polarities for (t >0+) ori have to use according to the new circuit?plz do show thecurrent direction for both t < 0- and t > 0+ ..and signsacross (+ & -) resistors and CApa andinductor,.plz explain each step
Explanation / Answer
have you learned the Natural and Step Responses of RLCcircuits without using laplace transforms? I do not have the book, so I don't know exactly what thatchapter teaches you
