Problem: The figure shows voltage and current graphs for a series RLC circuit.If L = 380μH , what is the resonance frequency?

FREE Expert Solution

Phase constant:

tan ϕ=XL-XCR

Resonance Frequency,

ωres=1LC

Impedance,

XL=ωL

XC=1ωC

Angular frequency,

ω=2πf

(2)

Φ = 60°

R = 2.5 Ω

Rearranging the phase constant equation:

R tan Φ = (XL - XC)
