Distinguish, differentiate, compare and explain what is the Differences between Light Emitting Diode and Photodiode. Comparison and Differences.
Differences between Light Emitting Diode and Photodiode
1. LED – Light Emitting Diode is forward biased whereas Photodiode is reverse biased
2. In Light Emitting Diode, recombination of electrons and holes takes place at the junction and light is emitted (hv). In photodiode, Light energy (hv) falling on the p-n junction creates electron-hole pair which increases photocurrent.
