Find the period of free electrical oscillations in the circuit if the capacitance of the capacitor is 0.2

Find the period of free electrical oscillations in the circuit if the capacitance of the capacitor is 0.2 μF, and the inductance of the coil is 0.8 H.

We will calculate by the formula

T = 2p * √LC, where

π – number pi;
L – inductance;
C – capacity.

To calculate, we translate the value of the capacitance into farads

C = 0.2 μF = 0.2 / 1,000,000 = 0.0000002 F.

Let’s calculate the period

T = 2 * 3.14 * √ (0.8 * 0.0000002) = 6.28 * 0.0004 = 0.002512 s.

Answer: 0.002512 s.
