A certain diode has a reverse bias current of Now this diode is connected in forward bias in the circuit shown, 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 80 mA will flow at room temperature (293 K). (b) Under the condition de-scribed in (a), End the voltage drop across the resistor.
