Answer 2

Calculating the Cyclical Frequency of an Oscillatory Circuit

To calculate the cyclical frequency of the oscillatory circuit containing a capacitor with a capacitance of 800 pF and an inductor with an inductance of 3.9 µH, we can use the formula:

Cyclical Frequency (f) = 1 / (2π√(LC))

Where: - C = Capacitance (in Farads) - L = Inductance (in Henrys) - π ≈ 3.14159

Calculation

Using the given values: - C = 800 pF = 800 × 10^-12 F - L = 3.9 µH = 3.9 × 10^-6 H

Plugging these values into the formula: f = 1 / (2π√(800 × 10^-12 × 3.9 × 10^-6))

Result

Calculating the value: f ≈ 1.21 MHz

Therefore, the cyclical frequency of the oscillatory circuit is approximately 1.21 MHz.
