A series LCR circuit resonates at a frequency of 850 Hz. If the half power points are obtained at frequencies `f_(1) = 750` Hz and `f_(2)` = 840 Hz then calculate the Q - factor of the circuit and bandwidth.

Explanation

To solve the problem, we need to calculate the Q-factor and the bandwidth of a series LCR circuit given the resonant frequency and the half-power points.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Resonant frequency, \( f_0 = 850 \, \text{Hz} \)
- Half-power point frequencies, \( f_1 = 750 \, \text{Hz} \) and \( f_2 = 840 \, \text{Hz} \)
