Consider the following statements: A. The junction area of solar cell is made very narrow compared to a photo diode. B. Solar cells are not connected with any external bias. C. LED is made of lightly doped p-n junction. D. Increase of forward current results in continuous increase of LED light intensity. E. LEDs have to be connected in forward bias for emission of light. Choose the correct answer from the options given below:

Options

  1. AB, E Only
  2. BB, D, E Only
  3. CA, C Only
  4. DA, C, E Only

Correct answer

A. B, E Only

Step-by-step solution

LED is highly doped, with different materials for different colours. Increasing forward current only increases light intensity until a certain maximum.
