What is the period of free harmonic electromagnetic oscillations arising in an oscillatory circuit consisting of a coil with an inductance of 0.8 H and a capacitor with a capacitance of 20 pF?
Task data: L (coil inductance) = 0.8 H; C (electrical capacity of the capacitor used) = 20 pF (20 * 10 ^ -12 F).
The period of free harmonic electromagnetic oscillations that have arisen in the considered oscillatory circuit, we define by the formula: T = 2 * Π * √ (L * C).
Let’s make a calculation: T = 2 * 3.14 * √ (0.8 * (20 * 10 ^ -12)) = 25.12 * 10 ^ 6 s.
Answer: The period of free harmonic electromagnetic oscillations is 25.12 * 10 ^ 6 s.
