In a p-n junction diode, not connected to any circuit

A PN junction diode when forward biased has a drop of $0.5 V$ which is assumed to be independent of current. The current in excess of $10 m A$ through the diode produces large joule heating which damages the diode. If we want to use a $1.5 V$ battery to forward bias the diode, the resistor used in series with the diode so that the maximum current does not exceed $5 m A$ is
