There is no initial energy stored in the circuit in Figure P10–41.

(a) Transform the circuit into the s domain and formulate mesh-current equations.

(b) Show that the solution of these equations for I2(s) in symbolic form is I2ðsÞ ¼ IBðsÞ ¼ R1CsV1ðsÞ

ðR1 þ R2ÞLCs2 þ ðR1R2C þ LÞs þ R1

(c) Identify the poles and zeros of I2(s).

(d) Find i2(t) for v1(t) ¼ 10u(t) V, R1 ¼ 1 kV, R2¼ 2 kV, L ¼

2 H, and C ¼ 0.5 mF.
