Q. In the circuit shown, if 𝑣(𝑡) = 2 sin(1000 𝑡) volts, 𝑅 = 1 kΩ and 𝐶 = 1 𝜇F, then the steady-state current 𝑖(𝑡), in milliamperes (mA), is
| (A) sin(1000 𝑡) + cos(1000 𝑡) | (B) 2 sin(1000 𝑡) + 2 cos(1000 𝑡) |
| (C) 3 sin(1000 𝑡) + cos(1000 𝑡) | (D) sin(1000 𝑡) + 3 cos(1000 𝑡) |
Ans: 3 sin(1000 𝑡) + cos(1000 𝑡)
Solution:
