Finding the forward current of diode

[whatphysics]

Homework Statement

A Si diode is operated at the room temperature (27 °C). For a forward current of 1 mA, the voltage VD is found to be 0.9 V. If the VD is 1 V, the forward current = _____ mA. Given that nVT = 26 mV

The answer is 46.81

Homework Equations

Shockley diode equation?

The Attempt at a Solution

I tried to use the shockley diode equation, Id=Is exp(Vd/nVt)
I subbed in values 0.9V and 1mA into eqn to get Is and then using newfound Is to sub into shockley diode eqn again with Vd 1V now. However, I didn't get the answer 46.81mA.

Is there an assumption that I have made wrong? Any help in figuring my mistake out is greatly appreciated. Thank you so much!

Oh my gosh, as soon as I was typing out my steps and I finally got the answer. Must have keyed in wrong values somewhere in the calculator previously.
So sorry for the trouble but thank you!
