Using the approximate equivalent model of a silicon diode and taking E=10 V and R=1k, what is the value of diode current at operating point?

Using the approximate equivalent model of a silicon diode and taking E=10 V and R=1k, what is the value of diode current at operating point? Correct Answer 9.25 mA

In the approximate equivalent model, the characteristic is assumed to be a vertical upward line at V=0.7 V. Hence, the current at point of intersection is determined to be 9.25 mA
