Question

An RLC circuit has a capacitance of 12 μF, an inductance of 25 mH, and a resistance of 60Ω. The current oscillates with an angular frequency of :

G1 Physics · Accepted Answer

For damped RLC oscillation, the damped angular frequency is √[1/(LC)−(R/2L)²]. With L=25 mH, C=12 µF and R=60 Ω, the value is approximately 1.4×10³ rad s⁻¹. Hence option B.
