Two statements are given below :
A. When the forward bias voltage across a p-n junction diode increases above a certain threshold voltage, the diode current increases significantly.
B. This current is called reverse saturation current.
Choose the correct answer from the options given below :
A. When the forward bias voltage across a p-n junction diode increases above a certain threshold voltage, the diode current increases significantly.
B. This current is called reverse saturation current.
Choose the correct answer from the options given below :
Options
- ABoth Statements A and B are true
- BStatement A is true, but Statement B is false
- CBoth Statements A and B are false
- DStatement A is false, but Statement B is true
Correct answer
B. Statement A is true, but Statement B is false
Step-by-step solution
Statement A describes the behavior of a p-n junction diode under forward bias. When the applied voltage exceeds the threshold voltage (or cut-in voltage), the potential barrier is overcome, and the forward current increases exponentially. Thus, Statement A is true.
Statement B claims this current is the reverse saturation current. This is incorrect because the current flowing under forward bias is the forward current. Reverse saturation current is a very small current that flows under reverse bias conditions due to minority charge carriers. Thus, Statement B is false.
Therefore, Statement A is true, but Statement B is false.
Answer: Statement A is true, but Statement B is false
Statement B claims this current is the reverse saturation current. This is incorrect because the current flowing under forward bias is the forward current. Reverse saturation current is a very small current that flows under reverse bias conditions due to minority charge carriers. Thus, Statement B is false.
Therefore, Statement A is true, but Statement B is false.
Answer: Statement A is true, but Statement B is false
