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-12)
• B. 10 cos (t + 55°) + 103/2 cos (2t + 55°)
• C. 10 cos (t - 35) + 10 cos (2t + 10° - tan-12)
• D. 10 cos (t - 35) + 103/2 cos (2t + 35°)
