The v-i characteristics as seen from the terminal pair (A, B) of the network of Fig. (a) is shown in the Fig. (b). If an inductance of value 6 mH is connected across the terminal-pair (A, B), the time constant of the system will be _______μ sec
-
- 0
- 1
- 2
- 3
Correct Option: D
The network, as viewed across the terminals can be described by
v = 8 – i × 200
∴ Rint = 2000 ohms.
| Time constant of the system becomes, T = | = | = 3 μs | ||
| R | 2 × 103 |
