Question

A triode value operates at Vp = 225 V and Vg = −0.5 V.
The plate current remains unchanged if the plate voltage is increased to 250 V and the grid voltage is decreased to −2.5 V. Calculate the amplification factor.

Answer 1

The amplification factor is 12.5.

EXPLANATION:

• For a triode value, the amplification factor is  
• μ = Plate voltage’s change  
• Grid Voltage change
• At constant plate current,
• μ = (δVPδVG)iP =constant
• μ = 12.5
• The triode has the amplification factor, which is 12.5.
• The amplification factor in the structural engineering is the ratio of the deflections of the second order to first order. The amplification factor is the amount to which an analogue amplifier increases the signal strength. It is also known as gain.
