The total charge that has accumulated on the positive plate of a capacitor varies with time. The charge follows q=At^2 for the first 4s.
a) Find the value of current at t=2,6,9,12,16 s.
b) Sketch the current i(t) as a function of time
c) What is the total charge that accumulates on the capacitor after 16s?
d) What is the average current between t=0 and t =16s?
What approximate minimum BER is required for voice signals, data signals and what is the approximate BER level for the optical fiber systems ?
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)
Calculate the current in the output of the source before and after the installation of the new device and The temperature sensor output is a voltage which is equal to the temperature sensed by the sensor. Design an electric circuit which can get th..
