Physics · Transient Response
An ideal voltage source having a voltage value equal to 10 cos(10t + 20°) u(t) drives the series combination of R = 3 Ω and C = 140 F. The natural response of the circuit for t > 0 is proportional to:
- 1ke-3t/40
- 2ke-3t/20
- 3ke-40t/3✓
- 4ke-20t/3
Correct answer
ke-40t/3
