The given values are:

  • R = 20 Ω
  • L = 1.5 H
  • C = 35 μF
  • V = 220 V
  • f = 100 Hz

The formula for Q factor is:

Q = \frac{1}{R}\sqrt{\frac{L}{C}}

Substituting the given values, we get:

Q = \frac{1}{20}\sqrt{\frac{1.5}{35 \times 10^{-6}}} = 24.6

Therefore, the Q factor at this frequency is 24.6.

The formula for resonant frequency is:

f_r = \frac{1}{2\pi \sqrt{LC}}

Substituting the given values, we get:

f_r = \frac{1}{2\pi \sqrt{1.5 \times 10^{-3} \times 35 \times 10^{-6
