Quizplus · Accepted Answer

The resonant frequency of a series LCR circuit can be calculated using the formula:

f = 1 / (2π√(LC))

Where L is the inductance, C is the capacitance, and π is the mathematical constant pi.

Plugging in the given values, we get:

f = 1 / (2π√(10 × 10^-3 × 20 × 10^-6))

f ≈ 356 Hz

Therefore, the resonant frequency of the circuit is approximately 356 Hz.

The correct answer is C.
