Triode — UPSC CSE 1986 Physics PYQ
Buy PYQ Solution Manual →A triode has a transconductance (g_m) of 1,600\text{ micromhos}. The following table gives two sets of the plate voltage (E_b), the grid voltage (E_c) and the plate current (I_b).
| E_b | E_c | I_b |
| 250\text{ V} | -22\text{ V} | 12.6\text{ mA} |
| 180 | -16.5 | 12.0 |
Define the terms amplification factor and plate resistance and calculate them for the above case.
