### RLC Circuit Analysis Problem

**Problem Statement:**

A series \( RLC \) circuit consists of a resistor with a resistance of \( 80 \, \Omega \), an inductor with an inductance of \( 0.19 \, \text{H} \), and a capacitor with a capacitance of \( 20 \, \mu\text{F} \). The circuit is connected to a power line with a voltage of \( 120 \, \text{V} \) and a frequency of \( 60 \, \text{Hz} \).

**Question:**

What is the peak current \( I \) at this frequency? Express your answer with the appropriate units.

**Answer Input:**

\[
I = 0.64 \, \text{(missing units)}
\]

**Submission Feedback:**

- The answer submitted was incorrect. It is important to include the correct units of electric current in your response.
- You have 5 attempts remaining to correct your answer.

**Hints and Tips:**

- Use the formula for the impedance of an \( RLC \) circuit in series: 
  \[
  Z = \sqrt{R^2 + \left( \omega L - \frac{1}{\omega C} \right)^2}
  \]
  where \( \omega = 2\pi f \) is the angular frequency.
- Calculate the peak current using Ohm’s Law for AC circuits: 
  \[
  I = \frac{V}{Z}
  \]
- Ensure the units are expressed in amperes (A) or appropriate sub-units such as milliamperes (mA) or microamperes (\( \mu \text{A} \)).
