In a triode value for a grid voltage V_g=-1.2V , the phase current I_p and plate voltage V_p are given I_p=(-5+0.1 V_0),I_p in mA and V_p in volt . When grid voltage is changed to - 3.2 V at constant plate voltage of 150 V , a plate current of 5 mA is observed , then Amplification factor mu is

Answer»

25
5.5
10.5
16.67

Solution :Amplification FACTOR ,
`MU= R XX G `
`= 10 ^4 xx2.5xx10^(-3) = 25`
