NEET 2026 Physics question
Not in JEE Advanced syllabus
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:
Answer: (2)
Solution
Statement A is true: in forward bias, once the applied voltage exceeds the threshold (knee) voltage, the diode current rises sharply (roughly exponentially) with voltage. Statement B is false: this large current is the forward current,
