Question

I would like to know how to find the values of A1 and A2 in detail.

Solution 4
We now apply the initial conditions to get A₁ and A₂.
v(0) = 5 = A₁ + A₂
du (0)
dt
v(0) + Ri(0)
RC
But differentiating Eq. (8.5.1),
du
dt
At t = 0,
5+0
1.923 × 10 × 10-³
= -24₁e
-2A₁e-²¹ - 504₂e-50t
-260
-2A₁
From Eqs. (8.5.2) and (8.5.3), we obtain A₁
Substituting A₁ and A₂ in Eq. (8.5.1) yields
v(t) = -0.2083e +5.208e
-2t
-
50A₂
=
-0.2083 and A₂
-50t
(8.5.2)
= -260
(8.5.3)
= 5.208.
