A diode is connected to a forward bias to a battery of emf 5V and a series resistance R. In its V-I characteristics it is found that a minimum current of 1 mA flows at the knee point. The maximum value of R will be

View answer and explanation

Correct option: B

4.3\,K\,\Omega

Option B (

4.3\,K\Omega

) is correct because it is the maximum resistance value calculated using Ohm's law and the given voltage and current values at the knee point of the diode.
