Question

A junction diode is connected to a 10 V source and 10 to the power of 3 end exponent capital omega rheostate figure. The slope of load line on the characteristic curve of diode will be

  1. 10 to the power of negative 2 end exponent A V to the power of negative 1 end exponent    
  2. 10 to the power of negative 3 end exponent A V to the power of negative 1 end exponent    
  3. 10 to the power of negative 4 end exponent A V to the power of negative 1 end exponent    
  4. 10 to the power of negative 5 end exponent A V to the power of negative 1 end exponent    

The correct answer is: 10 to the power of negative 3 end exponent A V to the power of negative 1 end exponent


    If V is the voltage across the junction and I is the circuit current, then
    V plus I R equals E
    or I equals fraction numerator E over denominator R end fraction minus fraction numerator V over denominator R end fraction equals negative fraction numerator V over denominator R end fraction plus fraction numerator E over denominator R end fraction
    Slope of load lineblank equals negative fraction numerator 1 over denominator R end fraction equals fraction numerator 1 over denominator 1000 end fraction equals 10 to the power of negative 3 end exponent A V to the power of negative 1 end exponent.
