An input voltage V(t) = 10 √2 cos (t + 10°) + 10 √3 cos (2t + 10°)V is applied to a series combination of resistance R = 1 kΩ inductance L = 1H. The resulting steady-state current i(t) in ampere is

• A. 10 cos (t + 55°) + 10 cos (2t + 10° tan^(-1)2)
• B. 10 cos (t + 55°) + 10√3/2 cos (2t + 55°)
• C. 10 cos (t - 35) + 10 cos (2t + 10° - tan^(-1)2)
• D. 10 cos (t - 35) + 10√3/2 cos (2t + 35°)
