In the circuit shown below, the switch is closed at t = 0, applied voltage is v (t) = 100cos (103t+π/2), resistance R = 20Ω and inductance L = 0.1H. The complete solution of ‘i’ is? |
A. | i = ce-200t + 0.98cos(1000t-π/2-78.6o) |
B. | i = ce-200t + 0.98cos(1000t+π/2-78.6o) |
C. | i = ce-200t + 0.98cos(1000t+π/2+78.6o) |
D. | i = ce-200t + 0.98cos(1000t-π/2+78.6o) |
Answer» C. i = ce-200t + 0.98cos(1000t+π/2+78.6o) | |
