Welcome to AAC!

For homework, students are expected to show their work and Users will guide them to a solution.

Also post the values from the parameter file.

Welcome to AAC!

Also post the values from the parameter file.
VT = 0.25 V

Ig = 5 mA

Is1 = 30.72106 nA

Is2 = 10.30577 pA

Is3 = 562.6759 pA

Vgc = 7 V

I just need to understand the concept on how voltage is affects LED shortage.

Use the formula for calculating the forward voltage of each diode. Then add them together and see how that compares to Vgc.

What would the voltage across a shorted LED be?
