A PN junction diode when forward biased ...

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 mA` through the diode produces large joule heating which damages the diode. If we want to use a 1.5V battery to forward bias the diode, the resistor used in series with the diode so that the maximum current does not exceed `5 mA` is.
