If the function generator is set to output a 2.3V peak-to-peak sine wave with a DC offset of 1.8V, then what will the maximum current through the diode be in milliamps? Use R1=161Ω, and assume that the voltage across the diode is equal to 0.61V when the diode is forward-biased.

I use node voltage, -vs + rs*i + vd + r1*i = 0
vs = source voltage, rs = resistance for the function generator, vd = diode voltage.

Ends up being -2.95 + 50*i + .61 + 161*i = 0
i = .0111
Correct answer should be .01019
Any ideas what I'm doing wrong?
