In the normal operating region, the characteristics of a certain triode may be written as
`I_(p)=10^(-5)(160 V_(S)+2.22V_(p))`
Determine analytically the values of `mu, r_(p) and g_(m)`.

A triode is operating at E_(c)= -4V , E_(b) = 175 V and l_(b) =10 mA. Around this operating point, the plate characteristics are linear and the parameter values are mu =20, g_(m) =2.5 mA/V. If E_(c) is changed to -6 V with E_(b) = 175 V, the value of l_(b) is given by

A Triode is operating at E_(c) = -4V, E_(b) = 175 V and l_(b) =10mA. Around this operating point, the plate characteristics are linear and the parameters are mu =20, r_(p) = 8 Omega . E is changed top -6V . To obtain the same plate current the value of E_(b) should be

A triode has r_(p)=10Omega and mu=20 . Table gives the operating point with blanks. The values of E_(b1) and E_(c1) are

The table values of E_(b) , E_(c) , I_(b) for a triode The value of r_(p) in k Omega and g_(m) in mA/V are given by

The plate current in a triode can be written as i_p = k ((V_g + (V_p)/(mu))^(3/2) . Show that the mutual conductance is proportional to the cube root of the plate current.
