If ib is plate current, eb is plate voltage and ec is grid voltage the v-i curve of a vacuum triode is
ib = 0.003 (eb + kec)n. Typical values of k and n are
Answer : Option D
Explanation :
k has to be much higher than 1 so that grid is effective in controlling plate current n is not 1 because it is a nonlinear device.
