Reference no: EM13306045

A green LED has a forward voltage drop of 2.3 V.

a) Estimate the bandgap energy for the semiconductor that makes the green LED.

b) What wavelength is emitted from the LED? The green LED is in series with DC source and a resistor of 500 ohms as seen in the figure.

c) If the DC source is at 1.0 V, what is the voltage across the resistor ? the LED?

d) If the DC source is at 5.0 V, what is the voltage across the resistor ? the LED?
