Two figures are shown as Fig. A and Fig. B. The time constant of Fig. A is _ A and time constant of Fig. Bis _ B . Then
Options
- A_ A = 1 4 ~s and _ B =5 ~s
- B_ A = 1 2 ~s and _ B = 1 5 ~s
- C_ A =4 ~s and _ B =5 ~s
- D_ A =4 ~s and _ B =5 ~s
Correct answer
A. _ A = 1 4 ~s and _ B =5 ~s
Step-by-step solution
For circuit A , aligned & R _ eq =4+ 6 12 6+12 =8 , ~L _ eq =2 H & _ A = L _ eq R _ eq = 2 8 = 1 4 ~s aligned For circuit B, aligned & R _ eq = 10 10 10+10 =5 , C _ eq =0.5+0.5=1 ~F & _ B = R _ eq C _ eq =5 1=5 ~s aligned
