A `p-n` junction diode when forward biased has a drop of `0.5V` which is assumed to be independent of current. The current in excess of `10mA` through the diode produces a large Joule heating which damages (burns) the diode. If we want to use a `1.5V` battery to forward bias the diode, what should be the vlaue of resistor used in series with the diode so that the maximum current does not exceed `5mA`?
