If `Z= sqrt(R^(2)+(X_(C)-X_(L))^(2))` then give the phase relationship of current and voltage.

Explanation

To determine the phase relationship between current and voltage in an AC circuit given the impedance \( Z = \sqrt{R^2 + (X_C - X_L)^2} \), we can follow these steps:

### Step 1: Understand the Components
- Identify the components involved:
- \( R \) is the resistance.
- \( X_L \) is the inductive reactance.
- \( X_C \) is the capacitive reactance.
