Assume that the silicon diode in the circui shown in fig. requires a minimum current of 1mA to be above the knee point (0.7V) of its I-V characteristics. Aslo assume that the voltage across the diode is independent of current above the knee point.
What is the power dissipated in the resistance R and in the diode, when a current of 5mA flows in the circuit at `V_(B)=6V`?
