State any two characteristics of resonance in an LCR series circuit.

Explanation

To answer the question about the characteristics of resonance in an LCR series circuit, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Resonance in an LCR Circuit:**
- In an LCR series circuit, resonance occurs when the inductive reactance (XL) is equal to the capacitive reactance (XC). This means that the circuit can oscillate at a particular frequency known as the resonance frequency (FR).

2. **Expression for Resonance Frequency:**
