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.) a. z1=--1+j(Sqrt3)/2 and z2=-1/2-j(Sqrt3)/2 b. z1=-1/2+j(Sqrt3)/2 and z2=-1/2-j(Sqrt3)/2 c. z1=-1/3+j(Sqrt3)/2 and z2=-j(Sqrt3)/2 d. z1=3/2+j(Sqrt3) ...continues
A current of 1400 A exits in a rectangular (0.6 X 9.0)cm copper bus bar. The current is due to free electrons moving through the bus bar at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter and if they are unifomly dispered throughout the bus bar, then what is the ...continues
In electronic circuits it is not unusual to encounter currents in the microamperage range. Assume a 20 micro amp current, due to the flow of electrons. a) What is the average number of electrons per second that flow past a fixed reference cross section that is perpendicular to the direction of flow. b) Compare the size o ...continues
