Assume that the diode in Figure P8.9 requires a minimum current of 1 mA to be above the knee of its i-v characteristic.
a. What should be the value of R to establish 5 mA in the circuit?
b. With the value of R determined in part a, what is the minimum value to which the voltage E could be reduced and still maintain diode current above the knee? Use Vγ = 0.7 V.
With the internal resistance of 0.14Ω, what will be the minimal load resistance to ensure at least 84 percent of the power delivered by the battery goes to the load
consider two groups are students, where the first group has 7 women and 3 men and the second group has 5 women and 5 men. Agroup is selected randomly and then students in the selected group are randomly arranged. Suppose the probability of choosin..
A full-wave silicon rectifier is used with a power transformer to generate the DC output voltage for a low current application. Assuming the storage capacitors are sufficient to eliminate power supply ripple
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way using some device.
