Question

In the circuit shown (Fig). if the diode forward voltage drop is 0.3V, the voltage difference between A and B is :

  1. 1.3V    
  2. 2.3V    
  3. 0    
  4. 0.5V    

The correct answer is: 2.3V


    V subscript A end subscript minus 0.2 cross times 10 to the power of negative 3 end exponent cross times 5 cross times 10 to the power of 3 end exponent minus 0.3
    negative 0.2 cross times 10 to the power of negative 3 end exponent cross times 5 cross times 10 to the power of 3 end exponent minus V subscript B end subscript equals 0
    rightwards double arrow V subscript A end subscript minus V subscript B end subscript equals 2.3 volt
