A diode is connected in parallel with a resistance as shown in figure. The most probable current (I) -voltage (V) characteristic is

• Correct answer
  A

  
  
• B

  
  
• C

  
  
• D

  
  

Solution

In reverse bias only resistance R is considered, so Ohm's law is valid $\mathrm{V} \propto \mathrm{I}$
In forward bias initially current flows through resistance, then after knee voltage, it flows through p-n diode

Hence, the correct answer is option: 'A'.
