The amplification factor of triode valve depends upon the relative : (a) change in grid voltage (b) change in plate voltage (c) distance between the grid and the plate from cathode (d) change in cathode voltage |

So, it depends upon the distance between the grid and plate from cathode.</span></span></p> | |
