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. .

A P-N junction diode can withstand currents up to 10 mA . Under forward bias, The diode has a potential drop of 0.5 V across it which is assumed to be independent of current.
