An LED has a rating of 2 V and 10 mA. It is used along with 6V battery. The range of series resistance is

[A].	0 to 200 Ω
[B].	200 - 400 Ω
[C].	200 Ω and above
[D].	400 Ω and above

Answer: Option D

Explanation:

R = 75-268-1 = 400Ω.

R must be at least 400Ω so that current in LED does not exceed 10 mA.
