Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Vacuum diode (i) Controlled flow of electrons (b) Triode (ii) Three electrodes (c) Tetrode (iii) Two electrodes (d) Pentode (iv) Four electrodes
Choose the correct matching:
A
a-iii, b-ii, c-iv, d-i
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-ii, c-i, d-iii
D
a-ii, b-iv, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
A vacuum diode has two electrodes (cathode and anode), a triode has three electrodes (cathode, plate, and grid), a tetrode has four electrodes, and a pentode has five electrodes. This matches the definitions of these devices as stated in the NCERT context.
