A collection of pn junction diodes have reverse saturation currents that range from a minimum of 510^14 A to a maximum of 510^12 A.

A collection of pn junction diodes have reverse saturation currents that range from a minimum of 5×10^−14 A to a maximum of 5×10^−12 A. All the diodes are forward-biased with identical currents of 2 mA. Determine the range of forward-bias voltages that are applied to the diodes.
