In the circuit shown below, the switch is closed at t = 0, applied voltage is v (t) = 50cos (102t+π/4), resistance R = 10Ω and capacitance C = 1µF. The complete solution of ‘i’ is? |
| A. | i = c exp (-t/10-5) – (4.99×10-3) cos(100t+π/2+89.94o) |
| B. | i = c exp (-t/10-5) + (4.99×10-3) cos(100t+π/2+89.94o) |
| C. | i = -c exp(-t/10-5) + (4.99×10-3) cos(100t+π/2+89.94o) |
| D. | i = -c exp(-t/10-5) – (4.99×10-3) cos(100t+π/2+89.94o) |
| Answer» C. i = -c exp(-t/10-5) + (4.99×10-3) cos(100t+π/2+89.94o) | |
