Expert Solution

Step 1

Procedure for $Z_{t h}$ calculation

1. Independent voltage Source become short circuit

2. Independent Current Source become open circuit

3. Dependent source remain as it is.

Step 2

Now the equivalent circuit will look like

Here frequency is not given so let f=50Hz. so the reactance will be

$\begin{array}{rcl} X_{C 1} & = & \frac{1}{2 {πfC}_{1}} \\ = & \frac{1}{2 \times π \times 50 \times 0.02} \\ = & 0.16 Ω \\ X_{C 2} & = & \frac{1}{2 {πfC}_{2}} \\ = & \frac{1}{2 \times π \times 50 \times 0.05} \\ = & 0.06 \\ X_{L} & = & 2 πf L \\ = & 2 \times π \times 50 \times 0.25 \\ = & 78.5 Ω \end{array}$
