When a diode is forward biased,it has a voltage drop of $0.5\, V$. The safe limit of current through the diode is $10\, mA$. If a battery of emf $1.5\, V$ is used in the circuit,the value of minimum resistance to be connected in series with the diode so that the current does not exceed the safe limit is $.....\, \Omega$.
- A$100$
- B$50$
