A practical coil is placed between two voltage sources v 1 = 5 cos 1 t

A practical coil is placed between two voltage sources v₁ = 5 cos ω₁ t and v₂ = 10 cos (ω₂t = 60°) which share the same common reference terminal (see Fig. 9-54). The coil is modeled by a 5-mH inductor in series with a 10-Ω resistor. Find the average power in the coil for

(a) ω₂ = 2ω₁ = 4000,

(b) ω₁ = ω₂ = 2000, and

(c) ω₁ = 2000 and ω₂ = 1000√2 , all in rad/s.
