At off-resonance frequencies in parallel resonant circuit, the phase angle is greater than

Concept:

Parallel Resonance:

General circuit

At resonance, V and I are in same phase.

power factor angle (ϕ) = 0° 

and |Y| = |G|

Y_T = Y_R + Y_L + Y_C

At resonance

B_net = 0

At ω < ω₀ [I lag V] ϕ < 90° 

At ω > ω0 [I lead V] ϕ > 90° 

At ω = ω0 [I is in phase with V] ϕ = 0° {UPF}

At off resonance frequency, the phase angle will be less than 90° but greater than 0°.
