NEET Physics (general) Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Forward bias (i) Threshold voltage ~0.7V (b) Reverse bias (ii) Controlled flow of electrons (c) Vacuum tube (iii) Reverse saturation current (d) Diode current (iv) Exponential increase after threshold
Choose the correct matching:
a-i, b-iii, c-ii, d-iv
a-iv, b-ii, c-iii, d-i
a-iii, b-iv, c-i, d-ii
a-ii, b-i, c-iv, d-iii
Correct Answer
Detailed Explanation
In forward bias (a), the diode current increases significantly after reaching the threshold voltage of ~0.7V (i). In reverse bias (b), the current is known as reverse saturation current (iii). Vacuum tubes (c) are devices that allow a controlled flow of electrons (ii). The diode current (d) indeed exhibits an exponential increase after the threshold is crossed (iv).
