Question

Question regarding circuits.

Answer 1

the answer is 4/3 + 27.7 cos(20t - 56deg). I was able to get the second part of the answer using super position. However, i don't know where the 4/3 is coming from.

Answer 2

what differential equation did you solve?
and how do you tell the initial condition?
if you don't know I'm still browsing the internet

Answer 3

well, using super position, I first turned off the 2v voltage source. and then solved for v(t). then i turned off the current source and then solved for v(t) again. Then added these 2 v(t). That gives the second part of the answer.

Answer 4

and I didn't use any differential equation, i used phasors.

Answer 5

oh looking up that term :p

Answer 6

I'm not sure if @ganeshie8 knows about circuits but I will call him here just in case
