A light-emitting diode (

L E D

) has the voltage drop of

2 \mathrm{~V}

across it and passes the current of

10 \mathrm{~A}

, when it operates with the

6 \mathrm{~V}

battery with a limiting resistor '

R

'. What is the value of

\mathrm{R}

View answer and explanation

Correct option: D

400 \mathrm{~k} \Omega

Option D (

400 \mathrm{~k} \Omega

) is correct because it is calculated using Ohm's law, considering the voltage drop across the resistor.
