Question

The mutual characteristic curves of a triode are as shown in figure. The cut off voltage for the triode is

  1. 0 V    
  2. 2 V    
  3. – 4 V    
  4. 6 V    

The correct answer is: – 4 V


    From the graph it is clear that of for V subscript g end subscript equals negative 4 V comma i subscript p end subscript equals 0 comma so cut off voltage is – 4 volts.
