A practical coil is connected in series between two voltage sources v 1 = 5 cos 1

A practical coil is connected in series between two voltage sources v₁ = 5 cosω₁t and v₂ = 10 cos(ω₂t + 60°) such that the sources share the same reference node. See Fig. 9-54. The voltage difference across the terminals of the coil is therefore v₁ − v₂. The coil is modeled by a 5-mH inductor in series with a 10-Ω resistor. Find the current i(t) in the coil for

(a) ω₁ = ω₂ = 2000 rad/s and

(b) ω₁ = 2000 rad/s, ω₂ = 2ω₁.
