Is the diode “on” for negative values of V 1 ? Explain. b. Assuming V D1 >= 0.6V for the diode to be considered “on, “for which values of V 1 (in the table) is the diode on? c. Does V D1 change by 0.5V when V 1 changes from 2.5V to 3.0V? Why/Why not? d. Calculate the power dissipated by D 1 when V 1 =3V e. Calculate the power dissipated by R 1 when V 1 =3V f. Calculate the power supplied by the source, V 1 when V 1 =3V g. Plot I D1 as a function of V D1 using Excel and the data from Table 1...
