A certain diode has a reverse bias current of 1.05 A. Now this diode is connected in forward bias in the circuit shown below, in series with a resistor and with a constant voltage source of 6.0 volts. (a) Find the value of resistance R such that a current of 140 mA will flow at room temperature (293 K). (b) Under the condition described in (a), find the voltage drop across the resistor.
