Match List – I with List – II and select the correct answer using codes given below :
| List-I | List-II |
|---|---|
| (a) Voltage source in a branch | (i) Polar capacitor |
| (b) Hysteresis | (ii) Super node |
| (c) Non-bilateral | (iii) h-parameters |
| (d) Transistor small signal model | (iv) Avoid false triggering |
Answer: C
The matching is a-ii, b-iv, c-i, d-iii. A voltage source in a branch is dealt with by taking a super node in nodal analysis. Hysteresis is used in a Schmitt trigger to avoid false triggering by noise. A non-bilateral element, which has different behaviour in the two directions, is exemplified by a polar capacitor. The small signal model of a transistor is described by h-parameters. Option (A) gives a voltage source as a polar capacitor. Option (B) gives a voltage source as h-parameters. Option (D) gives a voltage source as false triggering. Only (C) matches all four.
