As we learnt in

LED (Light emitting diode) -

It gives out light radiation when forward biased .

- wherein

LED's are made of GaAsP  ,Gap etc .

(Require low voltage ,long life )

 

 P_{max}=\frac{V_{max}^{2}}{R}    or     V_{max}^{2}\leq P_{max}R

V_{max}\leq \sqrt{P_{max}R}=\sqrt{100}=10

Hence, Minimum Range can be 0.8 

Correct option is 2.

 


Option 1)

 0 – 5 V

This is an incorrect option.

Option 2)

 0 – 8 V

This is the correct option.

Option 3)

0 – 12 V

This is an incorrect option.

Option 4)

 0 – 24 V

This is an incorrect option.
